When visiting Yellowstone National Park or any parks in our region, there's a lot to consider. Will traffic be bad? What about the weather? Will I see elk, buffalo, maybe even a grizzly bear? And then there's something more basic. Will I be able to find a toilet that's clean, has toilet paper, and if I'm lucky, somewhere to wash my hands? You could be in for a surprise, since the park recently added squat toilets.
