googlemaps advises route 40, route 70 or route 40 changing to route 70 all pretty much same mileage and drive time..says 36 hours...
which is better highway (no 2 lane travel, if we can help it...), easiest driving... ?
and any recommendations for most pet-friendly hotel chains.. one more thing... dog parks along the way?
anything not to miss, as long as we will be passing right by?
thanks for advice!
