... from under a building, that is. I'd like to build a shed on our rural property, to use as a camp when we visit, and for a storage shed after we live there. I can build an 8X12 shed on a raised platform in a few days, but I'd like to not create a new ecosystem, if you know what I mean. I can handle snakes, mice, and bugs, but I'd like to keep bigger stuff out. Any suggestions for a quick/cheap way to keep the critters out? I'm also worried about keeping two-legged varmints out of the shed, but I won't leave anything of value in there.
