Looking for some info

Recently while camping in a canyon in Colorado, my wife turned to me and asked if there were any bucket list trips I would like to take in our RV. As I was contemplating the question 3 military jets went barreling down the canyon. The answer to her question came to me immediately. I would like to park our RV in a spot that would give us the closest best view of military planes running drills all day. I was wondering if anyone in this community could suggest a legal spot we could go to Basque in the glory, the USAF doing their thing? Thanks in advance!
