I'm partial to the now-defunct PLHL, Parking Lot Hockey League, which ran from 1996-2011 where I live. Started with ~40-min noon lunch-hour games in the back parking lot at work, evolved to Saturday mornings only, a full three 20min periods with a running clock, 150x50' so you ran a few miles and had noodle legs after. Had a few guys who played collegiate and Junior-B. As you'd expect, we had a ~2-ft tall amalgam of juice/pop/Gatorade bottles taped/glued together then aluminum-foil-wrapped to silver it up for the season-ending trophy.
