I wish that I could give Rem more than 5 stars. He was everything and more that you could ask for in a guide. We left our house at 6:00 am to beat the crowd at his request. We had no waiting to get into the park whereas the line to get in later was 4 miles long. In addition to the planned tour, he was flexible with the scheduling and completely satisfied our group of 7 that was aged from 23 to 75: a challenge that most people would run from. He was highly knowledgeable and just a general pleasure to be around. The highest praise that I can give him is that my entire family told him during our picnic lunch that they considered him a "part of our family" and to dig in and share our lunch with us.
