My family and I will be visitng Yellowstone/GT parks at the end of July. It will be the first visit for my boys (20 & 17). My wife and I have not been there since we visited 25 years ago as part of our cross country honeymoon.
Should I anticipate that it will be much different than I remember? Also...indoing some research I came across float trips on the Snake River. Are these wothwhile?
