'94 Corvette keeps killing its battery

Standard 'vette convertible. Only 40k miles and nothing too special in
terms of options. But, I've just installed the fourth battery in four
years. Each spring the battery is completely dead though I try to
start the car once or twice a month during the winter. It's garage
kept, dry, and rarely does it get too cold in the garage. This last
time I couldn't even "jump" it on the full 100 AMP charger setting.

AAA loves me. The repair shop that keeps putting in new batteries
under warranty hates me.

Climate control is OFF. Key is OUT of the ignition.

What could possibly be the problem her?. All the shop tells me is "you
have to drive it because we can't find anything wrong."

Thanks.
