For Alamogordo we've contacted Holloman Air Force Base and asked for their recommendation on the best place to hold a small rally right outside their gates.
If anyone thinks we're going in the wrong direction with these approaches, please let me know! Thanks!
If they would let you on the base, there is a great park with a static display of a number of fighters. Wish I could join you as I have a number of past ties to the base and the area, but Virginia is a little far.
You may want to check with the Space Hall of Fame in Alamogordo. They have been very receptive to such activity in the past.
