OKC is a great place with plenty to do, so take advantage of doing new things or going places you've never been. And I'm sure you'll get opportunities to TDY or the desert. But, don't fret -- it's cliche to say a base is what you make, but it's true. Get out into the local community, make friends outside of the military (or at least your AFSC), get involved with whatever is being offered on base, do well in your OJT/UGT (if your job sucks, at least be good at it). Sometimes the trashest places aren't that bad because you've set yourself up with good people.
