Just fly. You won't see much. You'll be on the highway so it's mostly signs you'll see. and maybe you'll see a cow farm or two but it's not worth the driving. I am wondering about your gf, did you agree to this? I don't know what sane woman would enjoy a 5 day drive. I don't even like driving from Ny to NJ lol

If you do it..... find some games. Australia and every other part of the world may be nice since it hasn't been concreted over... but the us... eh. I can tell you nj, ny, pa aren't too nice with the highways. With construction and the planted trees (of course to beautify the highway) and broken down cars and whatever else is on the road... eh. I am not sure past nj or pa, I've always flown. You do know the price of gas isn't kind either?
