...Adv. 16 moved out of Costa Mesa...
I believe A-16 in Costa Mesa is just known as Patagonia. I used to live in the South Pointe Apartments across the street. Went to many a Kurt Wedberg Whitney Clinics there. Yes, how convenient was that!
Having used to live in Irvine and Costa Mesa, there just not many sporting goods stores other than Sport Chalet, Big 5, etc.
Then there is the Bass Pro Shop in Rancho Cucamonga. Go and get there EARLY! More sporting good stores in the OC area.
I believe there is/used to be a sporting good store in South Coast Plaza, but I wouldn't go there.
