Two travel-ish web sites I frequent are Atlas Obscura and Messy Nessy. While there are plenty of non-travel articles at each, what attracts me is the content pertaining to offbeat travel to offbeat places. In particular, MN has their Don't be a Tourist odd destinations section, while AO has Unusual Trips, which is exactly what it sounds like. But like I said, there's plenty of other stuff there too.
Go have a look around.
Obligatory Cut-and-Paste Graphics
ps: Was going to go road biking along the seawall, but a quick check outside showed heavy lightning-bearing clouds with "DARWIN AWARD" inscribed upon them. So much for that idea. Think I'll do bills instead.
pps: A listing of the top ten most educated Darwin Award winners here. Embarrassing, and I have no desire to make it eleven. Especially not while wearing lycra with a block of styrofoam strapped to my head.
