A bit of an improvement over the Tempe location. A little bigger, nicer looking inside, less homeless people peeping in your car windows.
Easiest way to get here is on I-10. Exit on Ray Road heading east. Turn right at the first light immediately after the I-10 overpass, in fact the intersection is still tilted from coming downhill from the overpass. As you exit I-10 and turn left onto Ray Rd, stay in the right most lane and hit your turn signal, it's really close. If you miss the turn, go to the next light (56th St) and turn right, then go down to the first right past the mall buildings which takes you back to 54th St.
REI is near the middle of the mall on the west side of the street. The sign overhead now says REI Co-op, not sure why the name changed.
I just hope they keep the rude pushy sales people out of this store, it pretty much ruined the Tempe store.
