You bet....., the area to the west of the Henry's airstrip, follow the road through the pass, it'll open up into a huge valley with a couple lakes and not much else, I believe it is called the Red Rock Lakes area, I've also heard it referred to as the Twin Lakes. Fly far enough and you'll hit Dell, and a possible eating place not too far from the strip there (5 or 6 thousand long and paved, after a local with a G5 moved there and paid to improve it). The wide open area is fun to play around in, mostly just you and a few cows and lots of birds there.
There is also a dirt strip I first heard about from a Husky pilot, I'll see if I can google earth it, OK I'm back: it's 44 degrees 23' 01.57" N and 111 degrees 17' 06.67" W. Or at least in that general area.......... Also check out the water falls, just follow the river from Island Park to the south, they are hard to miss, it is a big tourist site so there is a road there also. The convinence store near the Henry airstrip is open again, real handy and close. The IMAX theatre in West Yellowstone, they have loaner bikes at the airport. From there it isn't too far to the Teton National Park, not bad views over that directionm in fact it's all good!
