My Wife and I are in the early stages of planning a Sep, 2008 road trip.
We have two weeks, Sep 6-21, and are considering a loop comprised of Denver to Grand Teton to Yellowstone to Mt Rushmore and back to Denver.
What other sights/locations/municipalities should we make sure we 'don't miss' in this loop?
Anything else that would make widening this loop worthwile?
We want to see as much as we can, so since we are live in Central Texas, we'll cut off 1800 (roundtrip) miles by flying to Denver and renting a vehicle of some sort to make the loop, returning to Denver for our flight home.
Neither of us have ever been that far north that late in the year, so what should we expect (weatherwise) during that period? I realize weather can be unpredictable, but do we need to worry about getting stuck in a blizzard during September?
Would it be worthwile to rent a 4X4 if we really don't plan to offroad?
Any and all suggestions are sincerely appreciated!
