Yeah forgot about the Rockies. Trucks are required by law to chain up when the lights are flashing on those signs posted everywhere along I-80, and presumably other highways as well. They also barricade the entire highway if it gets bad enough. 12 years ago on my trek back to MA, I narrowly missed the road closure during a May blizzard through WY & Western NE. Almost got killed several times though. God was my co-pilot that day, FOR SURE!
