Staying Outside Yellowstone?

Just got back from a trip to Colter Bay campground for fishing Jackson Lake and took one day and went to Yellowstone. Took off about 8:00 that morning and went to Bridge Bay and looked at the bay and talked to a great couple in the convenience store, to Fishing Bridge to see if the otters were there yet, drove up to Canyon and took some pictures of the falls with the hundreds of other folks there and then went to the village for a hot dog lunch. Then, over Dunraven Pass to Tower Junction over to Lamar Valley, saw some beautiful Mountain Sheep rams and a ewe, a black bear climbing a tree and too many Bison to count. Then back around to Mammoth and down to Norris Junction past Old Faithful and a stop for ice cream at Grant Village. Got back to the campground around 7:30 or so and had a late dinner. We didn't get out and see all the features and we don't hike much at all. So, this was mostly a drive and see trip but it can be done. We also went to Leek's Pizza on Jackson Lake with some really great pizza and good beer, sitting outside on the deck overlooking Jackson Lake and the Tetons. We have done this trip a number of times, usually not quite as long and we do stop at the features most of the time. Besides, with the trip from Colter Bay, you have numerous opportunities to see wildlife on the way there and back.
