River or lake beer. Beer that has been in an ice chest for a few hours and you enjoy while tubing, kayaking, swimming, motor boating, etc. on a river or lake.

It is important to note that this is NOT the same as a beach beer OR fishing beer; which are similar, but distinctly different beers for reasons I can’t fully explain.

Hm. River or lake beer for me is a bunch of beers tied together and lowered into a body of water. Usually less than 1m is enough to keep it cool. It’s a different coolness.
