I have no idea what route we are taking (got the uhaul though!). Coming from Seattle - any suggestions?
You should definitely take I-80 as opposed to I-90 for the last leg... I think they meet up somewhere around Chicago, and then I-90 heads more northerly, along the Great Lakes, than you need to go. But I-80 ends on thre George Washnington Bridge -- a great way to enter Manhattan, complete with sprawling view and convenient access to the West Side Hwy.
Exciting adventure! I did it in reverse, when I moved to SF from NYS, once upon a time.
