Most of my fly fishing is outside san diego. Cascabel on the San Miguel river out telluride two weeks ago, the month prior Shoshone River out of yellowstone and cranston river Wyoming. Attached is the San Diego fly fishers news letter that will give you some ideas. Similar to Beach n toys, the club is very welcoming if you want to check them out. The new letter has upcoming trips to the flats in San Diego bay, cuyamaca amongst other spot for fly fishing. Just FYI love my tenkara rod for backpacking. If you haven't tried one, I highly recommend it. Did high sierra trail and Kern river last summer with good success.
Cheers
