I don't think they're going to bring any gliders - probably the 1-26 hasn't been taken apart for trailering in 10 years. The guy with the Libelle is planning on going down, but I don't think he's bringing his ship - it probably would not fit in anyway.
We did have a good day last weekend - of course I missed it. There were no instructors available and I needed to run errands all day anyway so I didn't go to the airport.
That was the day the temps were just right for a comfortable day. The Libelle disappeared for another 3-5 hour odyssey, and the Cirrus the 1-26 and the L-13 all shared the same thermal for about 90 minutes. I wish someone could have taken pictures of that.
