CJR I ended up there after going out to California to do a job, I had some time before I had to be at my next job in Florida. Instead of flying home I bought an old pickup truck in California and drove around the northwest United States for a couple of weeks. I slept either in the back of my truck or the cab depending on the weather.
While I was at Yellowstone I just drove around to see the thermal springs, Old Faithful, and especially the animals. Bear, Elk, Bison, Big Horn Sheep just roaming around....it is an amazing park.
If you go in through the Jackson Hole entrance you will see the Grand Tetons....... they are unbelievable.
To be 18 again.... that was a long time ago, but I'm sure it hasn't changed much....You will not be disapointed
