Sam was great. He was extremely prepared. Even had a telescope available so that we could see the mountain goats that he somehow spotted with his necked eye as he was driving. Amazing. He was willing to stay as long as we wanted or do things in any order we desired. All with an eye to getting us back to our ship on time. He was knowledgeable about what he was showing us and even mixed in some humor from time to time. And the van was quite comfortable. I would recommend highly.
