Just went to my local skate park. Absolutely swarming with small childern on bikes. They were mostly accompanied by grandparentswho were in various states panic and or ignorant bliss. I sat for a while observing. After nearly and hour I decided that there were absolutely no safe lines to skate without squashing the little fuckers. I then produces a dustpan and brush from my backpack, (not my first rodeo) walked round the park clearing up broken glass, and promptly left. The End.
