Yellowstone and weather in July / Aug
I am contemplating a trip to yellowstone and seeing Old Faithful in July or August. I have a couple questions. My hubby and I are both disabled and am wondering how this would be heat-wise and people-wise? I looked it up and it said the average temperature is about 76, do you find this so? Also, are there so many crowds there that we wouldn't enjoy ourselves? I am in the DC area and I know how the summer months can get, but August can be quiet as people tend to start getting ready for back to school. Thank you very much for your opinions.
