Dan Hartung at lake effect describes hashing, which is new to me but, I agree with Dan, sounds like it would be wicked fun for the right people. “Hashers play a modified game of the schoolboy game Hares and Hounds, basically hide and seek in reverse. The game involves people who lay out a trail, hares, and hounds who follow the trail. Usually it’s chalk, but flour may also be used. The main modification is that hashers (optionally) drink, before, during, and often after a run, turning them into what they call “a drinking club with a running problem”. Hashers tend to call each other by rude and sometimes obscene nicknames. The Chicago club has been featured on Wild Chicago, and I’ve always been curious — it looks like a fun crowd.” As he points out, here’s a Washington Post article about the phenomenon.
