Hi all.This will probably get moved from here,but here goes.I`m taking my daughter to see Muse at Wembley next Sunday and we want to go to Camden first to buy some trendy gear.Now,hubby is driving us to an underground on the outskirts where we`re gonna leave the car.Can we buy a ticket to use on the underground all day and if so is there a special name for it and how much is it likely to cost?
