Been there once and can’t wait to go back but will stay at the Old Faithful Inn at least one night. We did all the entrances and stayed way to long and had to drive back home Straight through to get back to work and that about killed the wife and I. I’m going to buy a small fire extinguisher of bear spray when I go back. We were at one of the stores in the park and was talking to a guy that works there about the bear spray and he said it works 100% of the time if you can wait until the bear is so close you can get it in their mouth and eyes but not to many people can wait that long 😆. Like idiots we didn’t buy any!!! We went and looked at a waterfall and came back and hopped in the vehicle and drove down the road and turned around and came back and looked over and their was a grizzly right where we had been. The only major traffic jams we had were from grizzlies and then the park rangers would be along pretty quick and give us all a tongue lashing and to get back moving.
