I now think anyone going to Yellowstone this time of year needs to check conditions daily. I "almost" visited a few days ago. I thought mid-May would be an ideal time of year, after the worst winter conditions, yet before all the tourists arrive for the peak season. A couple of the roads were still closed for the winter, but I was planning on coming in through Wyoming. I spent the night at an RV park between Thermopolis and Cody and the manager gave me the news that they had also closed both Wyoming entrances due to rock-slides. I decided to continue on up to Montana, but save the park for later. Perhaps I will try again just after the summer season.
We spent two weeks in Cody early in September and the weather was delightful on the whole. It's a long drive into Yellowstone from Cody (50 miles to the gate, 102 miles to Old Faithful), but the park was almost deserted (well, relatively). Hardly any traffic, even in the popular areas; lots of bison and elk to see. We went into Yellowstone through both the East entrance and the North entrance.
