I went to the airforce right out of high school and at my 3 year mark or so, I seriously thought of cross training into sat ops or EOD. I am glad I didn't now. :) But I had always wanted to be as close to the hot spots as I could get, but in the back of my mind, I thought I may not like it as much as I thought I would down the road. I decided to get out at my 4 year mark and have no desire to be in the hot spots now...I agree that the money isn't worth it if you don't get to come back and enjoy it.
Thanks so much!
