Good to hear you made it home ok.
That autosock looks interesting. It would have been a lot less work than installing chains in the cold back when we would take the kids to Yosemite to play in the snow. That reminds me I still have a box of tire chains taking up shelf space in the garage that I should get rid of. I don't them here as folks have the good sense to wait for the snow and ice to melt. Not to mention they wouldn't fit any of our current vehicles.
