Tank...
There are several T-6 drivers, me included, who have boats - Malibu, Tahoe, Moomba, etc...nothing as large as your boat.
DO NOT put your boat in Lake Columbus unless you want to flush your entire engine 4-5 times, plan on hitting a submerged tree, run over a log, etc. Best thing around here for fishing by far, but, not for "pleasure boats".
Most of us run our boats on Lake Tuscaloosa - VERY nice lake, but, a bit choppy. Lake Lowndes is also close, but probably too small for your boat. There is no public swimming in Lake Lowndes, but I use it for maintenance / burning gas. Two boats max on Lowndes and then it gets crowded. The Rez is down in Jackson - about 2.5 hours away - and is the same distance as Pickwick.
We have Verizon, and it is the best service around. Don't change.
The city school system here is PATHETIC....read: anything that feeds into Columbus High School. Depending on your financial situation, there are 2 private school options: Heritage Academy and Emmanual Baptist. I know for a fact several parents who pulled their kids out of Heritage and put them in Emmanual. Heritage is MUCH larger than Emmanual....less than 10% of the base populace sends their kids to these schools.
The most popular school district is Lowndes County ISD, which consists of West Lowndes (aka ghetto), New Hope (about 30 minute drive) and the MOST popular schools - Caledonia (which is where we send our kids). We have a 5th grader, and the Elementary School is fantastic...just received the states top honors, etc. Caledonia is probably recognized as the best option in the area.
What you'll find is that the jobs available are hit or miss. If you want to live close to the jobs, you are looking at the poor school district. If you are looking at Subdivisions -- Sherwood Forest area is popular (mostly married w/no kids though), about 8 minutes to the base. This subdivision feeds into the CIty schools - but is closer to the town. Oakdale Park is also very popular, and is where we live - feeds into Caledonia. Housing market here is "eh"? More things to rent than buy (check out www.militarybyowner.com or www.ahrn.com). No need to go thru a realtor if you plan to rent. We found our house by miracle. Listed as "For Sale by Owner" and had been on the market for nearly 6 months. No bites, and the owners (who are military) had to front two mortgages. We signed a 2 yr lease to ease their burden...so, if you see something you like, and you want to rent, call the owner and ask!
If you see something you like, PM me the area and I'll tell you what I know.
What type of job are you looking?
