Guys,
I had some extra time today after finishing some business in Amarillo, Texas so I Googled "control line in Amarillo" and up came a flying site at "Thompson Park", north of Amarillo off route 287. It stays light out till almost 9pm this time of year and it was "stunt heaven" weather. So I had dinner and took a drive out there figuring someone had to be out.
Well, I found the site, great facility, one paved concrete donut circle and two grass circles all had cement center pads. Paved parking is close to the circles. Also have electric power plugs (would be great for electrics, but bring an extension cord as the plugs are on a pole about 6 ft up). Unfortunately, no one was flying. Don't know who is flying out here the main concrete circle didn't look like it has been used (no oil spots on the circle anyplace) for a while.
Guys this is a great site, maybe they all fly on the grass in the mornings. If you are in the Amarillo area check this site out.
Best, DennisT
