My nondiving son has just moved to Madison. So I expect to be there a few times in the next few years probably in the Spring/summer/Fall. What are the options for local diving? Quarry, Lake, ?? I do not mind lower viz but do like to be able to see. Probably just rent gear for a day or two but might bring own regs, mask, and computers. Like to keep this sort of diving 80 ft or above. Would not have buddy but do not mind renting a private DM.
