My aunt is going to be visiting the US from overseas in a couple of weeks and really wants to go to Yellowstone. She's 68, doesn't drive, but quite adventurous. Oh, and traveling solo. How can we help her make this happen? We've been to Yellowstone, but we flew to Bozeman and rented a car. Since she doesn't drive, we'll need to find some kind of outfitter or tour group she can join - she only has a couple of days she can spend there. Any suggestions?where should she fly into, and anyone know a tour group she could join for a 2 day trip to Yellowstone? Thanks for any leads or info!
