The original Crawloween has been held in Moab, Utah -- there may be other events with the same name out east now.

The one in Moab is NOT being held on Halloween weekend, <img src="/forums/images/graemlins/nana.gif" alt="" /> <img src="/forums/images/graemlins/smile.gif" alt="" /> as has been the case for most of the past few years. The motel rates in Moab typically drop starting Nov. 1. So it's just after that. It's not "organized" by anyone, there are no pre-determined trail runs, and there's intentionally never any website or public announcement about Crawloween. That's for the purpose of agreeing with BLM requirements of keeping it very low key and fairly small so no permits are required. I know this because I've attended a couple Crawloweens in the past several years.
