Holy cow, Zombie Raider! That's some space there! WHOA
I have a big storage unit that I keep Halloween, Christmas and other sporting gear, hunting, generator, etc in. Needed something for a 17' aluminum canoe originally, haha... But after building my upgraded cemetery columns two seasons ago, there was no way I could have them in my garage, plus I like to keep my garage uncluttered. And I got sick and tired of schlepping my cemetery fencing up to the attic every year. Storage unit worth it.
I run by regularly to make sure everything's fine, but it's not climate controlled so I usually have to do some monster mud touch ups and such each year. I was worried when Harvey hit us last year but the storage place was OK (whew).
