The guide, Andrew was wonderful. Very informative, professional, and fun. The only 2 negatives were, the van was uncomfortable. Difficult to get in and out of, especially for older citizens. Also, there was no microphone, so with the air on and being in the rear of the van made Andrew very difficult to hear. The other issue, we were provided sandwiches on the van (passed out). It would be far more preferable to stop and picnic. In spite of these matters, it was a great excursion and I was glad we participated.
