I'll probably be digging for clams at Clam Gulch this Saturday morning. How can I keep them alive until I get them back to the Anchorage area Saturday evening or even Sunday sometime if I stop and fish the Russian on my way home? I figured maybe just a bucket of saltwater, but would they run out of oxygen? Or maybe no water, just on ice. I'd hate to arrive home with a bucket of dead clams. Thanks.
