I have a Subaru Outback, but not equipped with winter tires, though I have driven in the snow often being from ohio... not sure how much the tires matter exactly... but I will have 4 small to medium animals and want to avoid winter conditions and mountain areas if possible... want to stay on major interstates (I think that’s the correct wording... but trying to avoid 2 lane highways). A border control agent during my global entry interview said if I head out through Amarillo, then sideways to cali, then up I would avoid winter conditions.... but interaction was very brief and I couldn’t get many details. I’m moving for work so care less about sight seeing just want to get there with the critters safety. I’m really hoping to do the drive in 5-6 days, due to work wanting me there ASAP... but am very ignorant how to find routes as fastest go through Colorado which unless someone tells me they have done some safe route in winter, I want to avoid.
