Balboa Park has a extremely nice range with standard ranged targets and a walking course. $2 lets you shoot all day. Parking can be a pain, especially if you get there towards the later part of lunch. Not many Trad guys shooting there but then again there was hardly anyone there during the week. I would usually have the range to myself from 1100-1300 Mon-Fri. Saturday/Sunday can be pretty booked, but no one ever gave a hard time about shooting a stick. Just archers hanging out. The "other" Larry (Can't find his TradGang name) sometimes shows up there as well as a handful of other guys. The range is sponsored by San Diego Archers (
http://www.sandiegoarchers.com/). There's two ranges that they run, Balboa Park and Morley Field. If you don't see any traditional guys at the Balboa Range, try stopping by Morley Field.
As for shops, you're pretty much limited to "Bow and Arrow" or "Performance Archery". I went to both, can't say anything bad about either. Performance is geared mostly towards compounds but they do carry a decent selection of traditional gear. Bow and Arrow I only went to once and they were pretty much gutted for inventory as it was right after Christmas. But they had excellent customer service and I got a fling a few arrows with the "other" Larry while I was there.
Enjoy the retirement and good luck adjusting to civilian life. I know I'm both looking forward to and dreading my retirement in 3yrs.
