places like Burnside and FDR (in philly) are pretty hardcore... I myself never have a problem shotting at these places... but then again i'm scarier lookin then most of the locals...lol... I would hang out with your camera, dont hang back to far as to not look like some weirdo taking candied shots... I also wouldnt try setting up remotes, just shoot with a hand held corded flash... you will get the vibe if its cool after a few shots... never ask "can I take you photo"... thats just creepy, at least in the skateboard world.... most time after taking a few shots, some of the better dudes will some times jocky to start doing better moves to show off.... even the coolest guys like to have there photo taken... I have only once been ask not to take someones photo.... it was Chris Cole , that little @#$@* .... and after watching him fall 1000 time trying the same sh*t over and over I seen why he didnt want me to.... lol.... so anyway go shoot those punks...
