may I ask why ?
Mostly because it literally crashed in the middle of a neighborhood with live ammo on it. The city wanted to sue the base, even though the base did all the cleanup and paid reparations and no one was hurt. I think they ended up dropping it.
I have found that even though Yuma is more military friendly than San Diego, it still lacks a lot. I miss Cherry Point. Now there is a supportive community.
Here is an article about it if you are interested.
