My local base has three squadrons that I was rushing, and they all had different opinions on this. They all understood I would apply and hang out with people from all three local squadrons, but one chief pilot was of the opinion that if you weren't applying everywhere else, it was an indication you weren't actually that motivated to join the reserve. The other two CP's thought this was crazy and that if you were local/established in the area, believed in the mission, and got along great with the group why would you apply elsewhere (unless you were turned down).
I ended up not applying elsewhere, sticking to my guns on why I loved it there so much, and still getting picked up at the next boards. I strongly believe that everyone's background and circumstances are different, and as long as you don't act like a tool, you won't be seen that way.
