My fiancÚ and I made the trip from Phoenix, AZ to Charleston, SC this summer and are now moving back up to Portland, OR where we used to live. We are leaving early December. My issue is this is a completely different time of year/route than what we traveled last time. He is totally indifferent about which way we go and thinks we should wing it, but I'm convinced otherwise. So, my question: which way should we go? Time isn't an issue, we could take two weeks if we really wanted to (but hopefully not- that sounds awful). I am wanting the safest way for travel during winter. I know it's hard to judge because we don't know the weather a month in advance, but a good idea of what mountain ranges/areas are total death traps would be nice. Any insight/information would be greatly appreciated. Thanks!
