Glendale motorcycles have been using an ally on the west side of 67th Ave about 100 yards North of Deer Valley. Sometimes there are three motorcycles at a time. They prefer 6pm to 12am but I have also seen them during the day. Sometimes they are South of Deer Valley on the west side. The other bad spot is on Bell Rd just west of 67th Ave (near the RV sales lot on the north side). They have been sitting there almost every night for two years now.
