Had an interesting experience on the trail today. I was coming off the trail on the very last stretch before you exit the woods, and if you are familiar with the trail, you can step it up a bit before you're out of the woods; when I see in front of me, half hidden in the shadows (it was about 8:00pm) two small logs laid on top of each other right across the track. I luckily was able to screech to a halt (sorry for the skid mark).
These had obviously been placed there on purpose, no tree was down, no other logs close by, so immediately I thought this was a trap. I picked them up and threw them to the side, and made my way to the parking lot. Pretty empty out there, just another cyclist getting ready to go out, and a small group of adults, some of them in some kind of uniform(?) under the shelter. I was looking for kids.
After I packed up, I looked up at the "upper" parking lot, and here are about 6 young lads, about 10 to 12 years old, getting in the cars driven by the uniformed adults. I made to go speak with them, but as I had no shoes on at the moment, I paused to put them on. When I looked up again, they were gone.
Perhaps they were the pranksters, perhaps not, but boy am I glad I had my eyes wide open.
