The guide was excellent and we enjoyed th tour very much!
The tour guide knew little or nothing about the High Line. He walked ahead of the group in most cases and the only ones that could hear him were the two people on either side of him. When we passed over the Chelsea Market he denied that it was the market and never explained that it was once the Oreo cookie factory. He was mostly aware and impressed with the famous (?) people who resided or once resided in the buildings we passed. Of all the tour guides we've had, he was the most ineffective. We did enjoy the walk.
What an interesting and fun way to spend a morning in NYC! A whole lot of people cared enough to work tirelessly for years to raise the money and do whatever was necessary to preserve and repurpose this piece of history. Our guide was wonderful and knowledgeable. The High Line is a NYC jewel.
