How should I prepare for my first PCS move?

Get an old school map, no GPS, and drive around for 2 days and learn where everything is.

Best place to live is Enterprise. Flight school is College part 2 and you want to be near the other guys in your classes (for studying, parties, etc.) Since aviation is cutting their numbers and Enterprise went on a home building spree in the past few years there are tons of apartments/townhomes that all look the same but are pretty cheap. With a roommate the price gets even better.
There is nothing going on in Ozark and Dothan is too far for the 330 wake-ups when you have the morning flight line shift. The army and especially Ft Rucker make inprocessing a breeze so you shouldn't have any difficulties once you're there. Since you're a cadet just talk to your cadre about setting up your move at the closest transpo/finance office (wherever you do your FTX's I'm guessing).

First, congratulations on completing your education and your ensuing commission!! PCS is stressful but you can make things a little easier on yourself by reducing the stuff you don't need (I'm assuming that you are just starting out so you won't have a lot of furniture and stuff like that). Make sure and be there with the packers and movers and watch what is going on. Just today a friend told me that his movers packed and boxed a trash can full of garbage (ick) when they moved his stuff last month. I always thought that was an urban legend but I guess not! Separate anything important and or valuable (for example wills, marriage documents, passports, jewelry etc.) and carry it yourself. If you can, have water or sodas for the workers and maybe some snacks. They appreciate your effort. The last time I moved, the workers asked us not to buy pizzas (too fattening!) so we got them sandwiches. Also, stay friendly (I've heard many complaints from movers about the attitudes that some officers cop during the process), but don't be afraid to call something out that is wrong. This is your stuff they are moving!! Above all stay flexible. And be prepared to find at least one thing broken (doesn't happen every time but enough). You can make a claim on anything you find broken or missing. Take pictures of your most expensive and hard to replace stuff. Also, get all your stuff insured under a renter or home owner policy for transit. Good luck!!
