This is all my fault, the wife and I we're wanting to go down to Eureka Springs Arkansas to look at the fall colors, and I seen that hammer field was having a flyin. I noticed on their flyer they banned 3d and helicopters and showed it to crash 99, looks like it is sponsored by the Dawn Patrol so wwI warbirds are going to be the favorite. My fault for poking the bear. Looks like they welcome all airplanes as long as you don't fly them in a 3d manner or have a helicopter. I think What stirred this up is the flyer says fly what you bring and that it is a Fun Fly. I love flying at the war birds over the Rockies and I think I can fly my yak 54 I'm going to take in a respectful manner. IMAC freestyle, just kidding.
