I took my 12 yo son with me to learn more about Yellowstone and go for a hike while vacationing from Georgia.I described our current activity levels for them to decide which hike was best suited for us. Sam conveniently and promptly met us near our hotel. We learned Sam had more than enough educational background and experience and that we were in safe and capable company. Our lunches and snacks had been thoughtfully prepared for our day. We were able to observe elk, bison, wolves, a coyote, a moose, a showdown between a black bear and a grizzly mom with her two cubs. We had an unforgettable day tailor made just for us.
