We had a great time in Grand Teton and Yellowstone National Parks. It took awhile to narrow our 1200 photos down to a more reasonable number of bests, but we've finally done it and have posted them on Picasaweb.
We hiked an average of 8 miles a day (Debbie was trying to kill me), and did our fair share of camping and backpacking in between stays in nice cabins or fancy hotels. We had great weather even though late September has a possibility of serious weather in the area - we only had chilly evenings and no snow.
We saw all kinds of animal life up close, including moose (closer than Debbie bargained for), elk, bison, and even a rare type of woodpecker. We weren't entirely disappointed that we didn't see a bear given how much camping and wilderness hiking we did.
The thermal features at Yellowstone are truly surreal - bubbling hot springs, giant geysers and roiling fumeroles.
Even after Labor Day there were plenty of people around all the easily accessible wonders and viewpoints. But as soon as we stepped just a few feet onto a trails we found ourselves surrounded by scenery and very few people.
Here's a couple photos that we hope you enjoy, but visit picasa for the rest:
