I definitely was not obeying this sign as I DID stop and I suppose it was not completely necessary for me to drive on in seeing that I don't live in Ophir.
The San Juan mountains have some of the most avalanche-prone areas in the continental United States. The San Juan wilderness areas also have the most active avalanche control and snow physics study areas in the country and is one of the most geologically diverse mountain regions in the world. I guess that's the price we pay for living in some of the cleanest air in the US, too. :)
Ophir has over 100 residents and our paper stated that they mostly enjoyed their time of being snowed in. They had dinner parties, some skied off of the top of their cars, and they enjoyed watching the controlled avalanches.
My Jeep looks small next to the plowed snow at the side of the road here.
