Oh my gosh, we were just talking about him Saturday after our ride. We had talked about the next ride being over to the wall and also riding the trace. We had no idea!! Hope someone will preserve the area. It is very interesting and the story behind its existence is incredible. I went there on a date in college, was the girls idea (I had no idea it even existed), and Tom took us on our own separate tour just to separate us from the retirement home that was there on a visit. I would love to go back again.
