man so today i went down to the local dirt jumps afer school. I got there, and from afar, everything looked okay. but when i went closer, i asw that they were totally eroded!! It looks like someone walked around the still-soft edges of every one and then dragged their tire around the dges and on the lips, brakes locked up. Considering i just bulit this 4 pack a week ago, it has not fully hardened(which isnt too hard in Mass.) yet. Sure, some of the erosion was due to the down purs yesterday but not all. Also, this happened once before 'cept that time someone just rode over the lips crushing them slightly. So, i put up a sign sayin "expert jumpers only". I guess it was the sign that made them do it this time. But it just gets me that someone in the same sport as I would stoop so low as to wreck jumps that were built by a fellow biker. People...
