What is the quickest, safest route between Boston and St. Louis?
My family is planning a cross-country trip (not until summer of 2008). We'll be visiting relatives in St. Louis and see that city as the real starting off point for our trek West. We want to get there as quickly as possible.
How long will it take? Will we have to stop one night or two on the way there? (My children will be 12 and 16).
Any recommendations for motels/hotels along the way?
