I see you're in San Diego - when you get certified, PM me. I work as a DM on a local dive charter out of Long Beach and I like diving the Yukon and Ruby E from the Lois Ann down there near you too. Eric, the owner of the Lois Ann is very vintage friendly.
We dive Catalina and the outer southern Channel Islands several times a week. The offshore rigs as well but you'll want a few dives under your belt before taking on that dive. One rig is 350 ft and the other is 500 ft deep. Most of the good stuff is between 30 and 100 - 120 ft - Get a Fish and Game license if you like scallops
They're as big as car tires on the rigs - well, not that big but pretty big.
Hurry up and get certified
