Just returned from a 3000 mile roundtrip vacation to Yellowstone , the Tetons and Bryce canyon . Each one is spectacular in its own way and pictures do not do them justice but here are a few anyway. Yellowstone is so big it makes it hard to get around to seeing it all , but we did. The standard pass they sell at the gate is a 7 day pass , and now I know why ,alot of driving if you want to see it all. The town of jackson and Jackson lake is a great place to hang around for a day or two. Bryce canyon has some great campgrounds inside the park , and the shuttle system they have makes it a breeze to get around and see all the sites.
