Lafayette is the closest city to my small town, and I wouldn't have thought it had too many abandoned places in it. But I discovered this old Catholic high school by accident a couple weeks ago and went back on Saturday. It's behind a chainlink fence, but there was an old man mowing the property when I went, and he let me wander around provided I didn't try to enter the building. (It's not safe, collapsed floors and such. And anyway it's all boarded up.) I don't know how long it's been abandoned; looks like a while, but things tend to fall apart faster in hot and humid (and bug-y and vine-y) climates like south Louisiana.
