To get to DS, in the middle of Leiston coming from the A12 you turn left at the crossroads (A1122 / Yoxford road), then turn left into an industrial site just before the railway bridge (I think it might be an old army barracks). DS is right at the back in the left hand corner so as far from the entrance as you can get.....just keep going, avoiding the potholes etc. until you're sure you can't go any further. Then turn left to get to the far corner (avoiding the tumbleweed) and it's there. It's not that obvious until you get right to it, but once there the line up of shiny old Honda's in the window give a bit of a clue...
The 'bike shop in Framlingham is also a must if you are in the area...it's like a museum with the perfect collection of old Brit iron hanging from the rafters, and lots of lovely oily smells!
