So my boyfriend and I are making a trip from Nashville to SF. This is both of our first trips across country and are confused about which route is better (i-70 to I-80 and switching in Denver or I-40). We looked up the distance and it is not anything of significance but we are concerned because of the weather and mountains. We leave Friday and are worried that on I-40 we might get some of the storm and possibly tornadoes left from Hurrican Gustav in Oklahoma and Northen Texas. On the flip side we are worried about how mountainous I-80 is, particularly in Nevada. But we have never taken either route. My car is in good shape and can definitely make the trip, but it is a little bit older (1995 Nissan Maxima), so we are a little concerned about that. I-80 seems like a much more interesting drive. Should I be worried about I-80 at all or just take I-40 through the desert?
