If you have never been there it is a little hard to find. I recommend arriving by 22nd Street:
Drive on 22nd Street to 4th Avenue.
There will be a Quick Mart and Santa Rita Park on the corners.
Drive north on 4th Ave.
Turn left on 13th Street.
Park anywhere near Safford Middle School and the corners of 13th Street and 5th Ave.
The entrance is on the east side of the building.
Beware of all the kooky one way streets in the map below.
