Doug,

funny you should ask. I lived in Midland from 1964 thru 1969, and while there, my family started sailing @ Lake Thomas.
While on the way from Denver to Austin, I drove around the lake about 6 weeks ago.
Should you end up relocating to Midland, shoot me an E-Mail. Iat won't take long, but I'll tell you everything I remember about Midland and sailing @ Lake J B Thomas.
