My opinons... Eels suck - use clams instead
OK, eels. Put them on ice but so the melt water can drain (or they'll drown). Sometimes after it is still needed to whack the TAIL on a rock or something, not the head.

I'm not a fan of putting them in the sand as the sand sticks to your hands then gets in your gear. And half the time you'll have no sand. Use burlap, old sock, or regular rag
