Grand Teton, Yellow Stone, Glacier National Park...
...that's the road trip I'm talking about.
It's a safari, it's spectacular views with a wide variety, it's fly fishing, it's hikes in the mountains. Just make you sure you get some pepper spray in case you run into grizzly bears (not kidding here, attacks are not that rare). Go with your boyfriend, go with your girlfriend, your friends, your kids, but GO! If it's just the two of you, rent a convertible Mustang. If it's with the kids, rent the motorhome.
One more thing, coming from Jackson's airport to Grand Teton, put the soundtrack of Laurel Canyon (the movie) on, track #9, Harmony by Clinic, it's part of the experience
