Halloween is the locals' holiday in Aspen, as the mostly tourist-free resort town plays host to the biggest annual offseason party of the year. Whether you're trick-or-treating with the kids in the North Forty or getting sloppy with the grown-ups at the Caribou Club as the members-only establishment throws open its doors to the public, there's something for everybody in a costume during Halloween in Aspen.

(Please note this is not a comprehensive list.)

The costume contest is scheduled to start at 11:15 p.m. between two Spazmatics sets, so don't be late. Tickets are $25 for general admission and $40 for reserved seats.
