Having been assigned to Leonard Wood, Huachuca, Hood, and Gordon - and having spent time in Drum, Mead, Irwin, and Polk - I would have to say Huachuca, Hood, or Gordon. Hood is one of the largest, with 13th COSCOM, 1st Cav, 4th ID, and III Corp Headquarters. There are several towns etc. nearby, and Austin is only 45 minutes to an hour away. Dallas is around 2 hours away. Disadvantages are that Cav is a pretty screwed up unit to be in - they do everything ass backwards. Pretty much everything is tactical with alot of field time. This may be good or bad, depending on your viewpoint. A huge advantage is that it's in TEXAS.
There are lots of post facilities, with two large PX's, and two good sized Commisaries. There are numerous shopettes, two movie theatres, two museams, and many other things.
Huachuca is located in the mountains of southern Arizona. Beautyful area with great weather, though the thin mountain air takes some getting used to. A bonus is that when you go to another post that actually has enough oxygen to support normal life your PT scores will instantly improve. Disadvantages are that the whole area is swarmed with illegal aliens. I remember Sierra Vista - which is right outside the main gate - to be a rather nice area. It's a much smaller post than many others, and theres alot of TRADOC troopies,so that may be a significant disadvantage. Tuscon is 45 minutes or so away.
Gordon has alot of commo types there, and there's alot of strat positions. Also a big TRADOC post. There's stuff to do off post, as well as on post, but I don't really remember much about it. I was there for a limited time on a TDY, so it was mostly work.
Drum is also ok, but it's kind of in the middle of nowhere. Evans Mills, which is pretty close to post, ust got a Walmart a month or so ago. My best friend is stationed there - in Asscrackistan actually - and he brought me on post once. The PX seems pretty nice, as is the clothing sales store. Upstate NY is a beautiful place - and mostly conservative - although it getts pretty brutal friggin cold this time of year. A plus is that you are real close to Canada, so you can expect to be at the spearhead when we invade
. A BIG disadgantage though is that it's located in NY state.
All of the above is, of course, my opinion. YMMV.
