If you need a disc, this place has an incredible selection - new and used. The used are a great value. The new are on the pricy side, but you're supporting local business, so... that may make up for it - you decide. Three walls of the shop are filled floor to ceiling with discs, plus two standing displays!
The two dudes working were friendly enough & gave us a map of the AZ disc golf courses (though it was unfortunately outdated/incorrect we discovered after driving to a couple).
There's an 18 hole course right off the parking lot but it's not the best - very crowded with groups of frolfers, water hazards through the whole course (which can be cool; but definitely tough for beginners), and it's shared with joggers, dogs, kids... not a real safe place to play (for the pedestrians).
The music in the shop was a little too loud for comfortable browsing... that's the only downside.
