On Dec 27th & 28th, we'll be there. Last year, it was in the 60s on those dates. However, the two previous years were in the 20s at night and 30s in daytime. At those temps, my family won't ride. You'll need thick insulated gloves, thermals, etc. for that. I'm trying to round up some friends to go with us, just in case wife/kids bail. We own a home on the Hooch near Creek Bottom ATV park, about 4 hours from DP.
