This pissed me off. While I can appreciate the skill required to skate well there's no excuse for vandalizing property. I saw some clowns scraping the Trinity Church steps once. Give me their addresses and I'll do some shredding on their cars. That would be totally gnarly right dudes?
I can confirm that it is my friend walking by in that video... Weird.
You should forward the link to your friend, he would probably get a chuckle out of it.
