Cool graffiti

Went for a bike run this morning and as I went through an underpass I was pleasantly surprised to find lots of wicked graffiti and lots of it.Though not a fan of it at all in citys and on buildings but in a place where seems to be out of the way or allowed and doing no harm i would say is fine in my eyes so long as it's proper painting and not just mindless graffiti!!!Who ever has been there has taken time in doing it ,even the paint must cost alot of money , a very interesting place and obviously well know for being a place to show your work off!!!!
