My husband is being transferred and going up ahead of time. Don't know if he'll stay up there or come back to Houston to help me move. Biggest issue is 3 cats. Looking for the quickest/safest route. Do I need a 4 wheel drive? I have read not totally necessary in Anchorage, but I am worried about the long ride up the Canadian coast. I hate the thought of shipping them..it would be like shipping my kids!
