A "crawl" (in England and it seems in Huntington Beach a "pub crawl") is typically an evening where you go from bar/pub to bar/pub sampling their (alcoholic) wares. You go on until you drop, which is where the "crawling" comes in. I've been on a few in London where we limited ourselves to 1/2 pint of each of the real ales each pub sold, which typically was at least 6 and could be much more, with a target of at least 10 or 12 pubs. It isn't wise to drive yourself to these do's.
Good fun if you can remember it. Come to think of it, if you can remember it it probably wasn't good fun.
