We went the other way, from Sharpsburg, GA to WI back in 95. Yeah, basements uncommon down there.

I remember a few different insects, chiggers & termites for starters.

We were just outside Peach-tree City, sure it’s grown even more since then. The roads were smoother, no road salt is easier on vehicles.

All the best with the move.

I live north of you about 60 miles. Safe in garage for 10 years with a golden rod. Not the first problem. My gun tools and benches are in the basement along with my other tools and shop. I do heat the area during the winter because I spend a lot of time there. AC in summer also. Never had a problem in either area, although I do keep any cast iron tops on the tools waxed every couple of years. Never had a problem with powder or primers there. Use good judgement and you won't have any problems.

Here in North Texas the summer humidity is terrible. I've never stored ammo in the garage. I have no choice but to store tools in the garage. If I put them in the house I'd have to sacrifice a room.
