And Maine grows the good clear blocks that last a long time. 10 pounders for $2.25 a piece are the norm, but '50's'(50 pound blocks) are still available in my area.
My old boat came with a pair of ice tongs for those '50's and the box, 10 cubic feet was designed with those in mind. I still have the ice tongs that came with the boat. Today, they freeze a handle right into the '50's', so my tongs are obsolete, Charlie.
