Rigs outside of Galveston

Went out early on 6/7/04 in a 21' Sea Pro to the North Jetty, things were slow all around. Headed out into open water after a few hours because the sea wasn't too rough and found 2 rigs almost straight off bolivar beachfront about 10 to 15 miles away. This was the first time we'd ever been rig fishing and shark seemed to be the only thing around. Are there any rigs within 20 miles of the galveston jetty that harbor good snapper, ling, or king fishin? Didn't seem to find them on those 2, and no more rigs in sight so we headed back that afternoon. Nevertheless, a good day to be out on the water.
