ok... if you're around on a saturday, go to the graphotism store(same as the magazine, yes). its only open at saturdays, located right next to Hackbridge station in south London. there IS a risk of getting mugged if you're not with locals and/or flash money/cans/tourist shit. but IF you're getting mugged its mainly other writers "just" after your cans. but usually it's allright. the store is about 30min train-ride from central london, in zone4 of the TFL system. for legal walls, follow this link: http://www.liquidfunk.co.uk/grafitti.htm but beware, some of the walls are not legal, or doesnt exist anymore.(like the one in Grove Park, thats been teared down.) if you're just looking for cool shops with nice clothes what ever, hit down to covent garden, and you'll get everything from skatebrands to carhartt store to adidas to diesel to magma to whatever style you like. have a nice time. i love it here.
