From 219N. Just past the Freshbay Seafood market and beside the new Elkins Visitors center turn right on to Elkins Avenue.
Continue up Elkins Avenue until you reach Johnson Ave on your right, second right(there is a Yellow Joeys Bike Shop sign at head of the road). Joeys Bike Shop is the first place on the right. I guarantee you can't miss it!
A map can be found here.
