But I suspect many of those service workers either have snow tires or chains on their 2wd. The pass can get a bit unnerving in a storm.
It's not too hard to get from Leadville to Vail, going over Tennessee pass instead of Fremont pass.
Motels in Leadville is not much more $60. But the drive is more of a hassle than from Frisco/Dillon when there's weather.
