After I-29, get on I-80 west through Nebraska then into Wyoming and take I 26-287 to the Grand Tetons and enter Yellowstone that way. Nice drive into the park. We stayed at Madison in May.Nice, centrally located campground. Make sure to go into the Old Faithful Inn. It's supposed to be the largest log structure in the world. The interior is beautiful. The food is good and the prices are decent. We saw a mother grizzly with 3 cubs on the way from Norris to Canyon.
