My experience at FLW, which ended in Aug 04, was a world away from what you are about to go through. (I was a unit 1SG). However, some things remain the same. It will be hot when you first get there, and rainy. Possibility of a late tornado, but slim. Snow starts in October.
You will be billeted the entire time (basic and AIT) in one of the newest facilities in the Army. It doesn't get better than that. Unfortunately that means you get the same NCO's all the way through. Don't piss them off!
Use the time you have to get used to running. MO is hilly, so plan on that. Practice pushups, situps and pullups. Get a light pack and walk at least one 5 mile walk a week.
When you get to go off post do not go to the hotels in St Robert. Go up to Rolla at a minimum, Springfield is even better.
Do not HOOK UP with anyone local! The rate for STD's is HIGH! Syph and herpes are 5-6 times the national average. It is not a something you want to take home.
The Rocking R is the best local club. The rest are SHT! The only strip club worth a darn is the big one up off 44. Don't bother.
The cabbies will screw you. Make sure you get a group rate, not an individual one. Do not (repeat, do not) stiff a cab driver. If you can't pay, walk.
Springfield is the best town to go to if you have a free weekend. It's closer than St Louis, and cheaper. If you must go to St Louis do not stay downtown (by the Arch). Stay is the Clayton district. It's a business district and the weekends are their slow time, so you get good rates. The downtown hotels have a major room robbery problem.
Walmart is the community social center. Everybody goes there. Including your DI's.
MO is rural. It's also meth central. Be warned. Other things of note include every other driver on the road after 10 pm being drunk, KKK still being active south of post, and stereotypical hillbillies a fact of life.
Everyone (I mean everyone) local is tied to the military. If you screw up they will let your Commander know. Even off post you will be expected to act appropriately.
Don't dick with the civilians. Most of them are ex-military. They can make your life miserable.
Understand that you are going to be the lowest of the low for a long time. Don't worry. You can make it.
If you get stuck on Post Detail, try to get selected to work at the Motor Pool.
There are computers available at the post library for your use. They usually don't let you know that. You can surf all you want there.
The MWR has a good trap and skeet range. When the weather is good you can also get with them for fishing and canoe/float trips on the Big Piney.
There is a good BBQ / picnic area across from the library by Engineer Loop. It's a good place to have a quiet party away from your DI's.
Write this down. 596-1927. That's the number for the official dispatch post taxi. You can use it provided you do not go near the barracks, PX, or housing areas. (The trick is to pick a official building near your destination and use that address.) Trainees are NOT told about this. It is much faster than the post bus.
The second best kept secret is Lake of the Ozarks. You can rent a 3 bedroom cabin there for about $40/a night. There's a marina with boats and jet skis, a general store, swimming, BBQ areas, and a nice resort town(Osage Beach) 15 minutes away. If you really want to live good go there on your free weekends. MWR is your POC.
Last, don't drink and drive, and don't get stupid drunk within 50 miles of post.
