3 step block
Usually the most popular obsticle at most parks.. is skatable to all abilities which is always a bonus
Wouldnt mind seeing one of these on the top of a driveway/hip, would be so much fun!
Would also like to add that stairs in a park do work. Personally dont think they stop the flow at all, just look at prissick plaza, the place is full of them yet flows perfectly. Put in the middle of a bank so they jut out they can be skated in so many different ways.
