this guided trip was by far the best we have ever taken. our guides name is Lincoln Baker and he did a great job. We saw many different animal species mostly because Lincoln made wise decisions about our route. We started earlier in the morning 6:30 a.m. where most the other trips we screened to southern loop of Yellowstone start around 7:30. There was an inversion causing fog and it seemed to have the animals a little more active. We saw two moose early in our travel followed by a modest herd of buffalo and a prong horn. We weren't going to make old faithful in time for the way the route and road was running so Lincoln made a great decision to run the route backward. We saw a large herd of buffalo and then the best treat wolves, 4 total after a young bison. Lincoln was quick to grab the spotting scope and tripod so we could get a good view of them. Lincoln was very Informative and knowledgeable, willing to share the trip experience with the group. I would recommend this tour group to all even if the price does appear a little prohibitive. To view everything while someone of knowledge answers your questions and expertly does the driving and navigation makes it worth it.
