    As an FYI, (inclement) Weather will not be a factor. No heavy moisture (or even clouds) to speak of, but the trof (mentioned earlier) is still in the fcst models, so some instability is progged as the pressure changes, but weather models are immaterial to the matter, since we are operating on a calendar model. But with the lack of pressure differentials, there may be a distinct lack of wind to channel the thermals.

    I'm looking forward to flying.

    Here is the Saturday, 30 May fcst for 11 AM at 700 mb, some 188 hours into the future:

    Another good Race Day, thanks Rex, Noelle, Staff, and fellow racers.
    Sun was filtered much of the day, wind never created difficulties, but coming from the SE or the SW , depending on your location at the time caused some consternation as to thermal location. I'd prefer a more prevailing southwesterly myself.
    Launch with three tow planes was quick, Key in OJ, 7V behind the cub, YE next, second wave was me in 88, then 1B and G3.
    I was off tow, mimicking what Key had said he had done and it worked for me too. 1 mile east of tree farm,

    climbed in 3 kts from 6 to 7-ish, searched for better air, tried to gather intel from YE, 7V and OJ, but had limited specifices, so I set out on my own to explore Snow - dumb idea.

    worked the windward side of snow at 6,000 but never having enough altitude to do a circle - only back and forth butterfly turns. I listened as Key, Ray, Jim all started...

    The all started above 7,500 ft and then Ginny reported getting to 9ish, so I headed to goat, found the lift and was able to do a start above 9,000 ft
    Everyone else was already ahead of me. YE reported having started earlier. I was tail end charlie.

    The CD changed it from a 3 hr race to a 2 hr and 15 minutes, and had increased the circle around the first TP from 10 miles to 20 miles.

    I had a good run from start to the first TP. Enroute I scribbled that since I started at 2:37 I needed to land shortly after 4:52 PM
    I had calculated the I need to leave sheet Iron on final glide at a bit after 3:52, since that was a 68 mile glide.

    I had caught up to Key, and had passed Ginny and Jim. I watched Key head south below me, he called his turn at 18 miles from Yolla. I planned to use more time, since I didn't want to fnish early and was not expecting any lift on final glide, so I kept heading north until I was 11 miles from Yolla. I headed south as Ginny and Jim came up and headed to the same thermal I had been in. They all turned in about that same area and headed south.

    It is a mystery as why we all read the same incorrect mileage to Yolla TP. We each knew that we needed to be within 20 miles of it and Key and I and both thought we were within 20 miles when we reversed to the south. Not certain if Ginny and Jim thought they were within 20 miles or not. That is an unsolved mystery. During the cold war (1965 to 1968 for me), the russians did meakoning along their SE coastline and when flying USAF missions along the route from Japan to Alaska we were regularly baited with false navigation beacons attempting to lure us into Russian Airspace. Maybe someone was jamming up our GPS signals (or making Yolla Peak appear closer than it really was) . Is that possible? - not a real question!! I suspect errors in software that was common to each of the gliders.

    Race was over for me at the photos finish...

    Not knowing I was done, I forged ahead with my action plan. I was feeling confident now. Only 7V could have a better speed than me at this point, since I was the last to start.

    I observed 7V heading north, but climbing well, so I made a 90 degree turn and used his thermal...
    then went south, and came back north

    I just needed to hit the southern edge of the Black Butte circle and I'd be on final glide.

    I was precisely on schedule on altitude and on time.

    4:10 PM to 5PM a good final glide, no turns, accelerating above 60 to 65 kts or so only during the last couple of miles.

    My entire flight was high - except fort the time spent on the south end of Snow before the start.

    The flight log itself:
    (Note: You will see that Russ is listed as the pilot on this log, but I had selected my self as the pilot prior to launch and it had displayed my name as the pilot when I checked it later in flight. I can't explain the mysteries of that nav equipment.)


    In any case, it was a fun day and I felt totally exhausted 30 minutes after landing.
    Even after I was informed about my malfunctioning nav gear, I remained in good spirits.
    I was hoping the others had enjoyed as much as I did, however, as it turned out, I think Ray was the one and only one to complete the course. It is always more fun for everyone when most participants complete the course, that's for certain.
    But it was good to fly again with everyone. I only hope that Key, Jim, Ginny and Larry all had as much enjoyment as I did.

    Edit several days later: Mystery Solved!
    Nav gear was not malfunctioning. Operator Error.
    When tasks are set into clear nav as "area tasks", the distance given to target is to the ring, not to the next turn point.
    Pilots using clear nav and thinking then were 18 miles from the TP were really 28 miles from the TP and 18 miles to a 10 mile ring. Lesson learned the hard way.
