Nice skating...
The tagging however... You guys who do this piss me off. For me, there's a difference between people who make REAL statements and tags, the real graffiti artists who make a veritable work of art on a building, usually something abandoned, and make an impact on the city environment. Those people i have respect for, they are decorating the city and making it look nice, they have talent, and it's enjoyable to look at.
Your guys' thing, is absolutely retarded and ugly. It takes no skill to tag a "name" like you do, it's in simple, ugly black and in the very least absolutely unimaginative. Also, you're vandals on a larger scale than most real graffiti artists. I can understand tagging a derelict place. I can understand tagging alleyways. I can even understand tagging public building front and other public property, with a message (see Banksy). I don't think it's validated in any way by the message, but i can understand it and appreciate it.
But you guys... You tagged some dude's van... his friggin personal property. You tagged a street sign, poorly, a billboard, disgustingly, but a dude's VAN?... What you do is not making any impact on the city more so than making it ugly to look at. Get some real skills, make some real art, don't simply throw a name up and claim it.
