I often run on a very large park here in Paris, which was actually one of the inspirations for Central Park, and I usually don't know which way I'm going cause I just take random trails and end up kind of lost.
On Sunday I was running through the woods there, kind of spacing out, and I saw a black tent, which I thought was weird. When I looked up, I was actually surrounded by a lot of those black tents, maybe 20 or so. They weren't easy to see from a distance because we were in the middle of the woods and they were black. Around me were also a bunch of transvestites staring at me and some guys dressed in all black and motorcycle helmets, who I assume were doing security there or something.
I got really nervous as they were all looking at me, and I believe what they're doing there is illegal, so I just picked up the pace to leave that place. For the next 200-300 meters I was still passing some tents like those, but luckily after that there were no more and no one came after me, so I just continued with my run and made a mental not to try not to pass by that area of the park again.
