Wow, interesting rock art area and I have another new place to visit! Good to see the Ted's out and about and hope your vision problems clear up soon-there are so many neat places out there you still for to see! Just the thought of losing your sight especially while out and about is terrifying especially when you think about all the places we go and explore.
I remember years ago (this is not meant to be a hi-jack) I took a group of mostly handy caped kids and some grown ups from the county out to a rock art site for a day field trip. An older gentleman who was blind was included in the group, I guess as an after thought by the county coordinator to give him an outing. Over the years I had led lot's of groups of people of all ages to lot's of different types of prehistoric and natural sites but how do you explain rock art to a blind person?
Earlier I had seeded the site with some old training arrowheads and let the kids look for them and then I explained what they were. I put one point on a rock and told the blind guy to reach out and grab it. He was in on the joke and we all laughed about it. As I led the group around the site one of the kids took his hand and led him around the rocky area as I explained what what was there, and (how do I explain this), he reached out to touch one of the rock art panels I was describing it and I grabbed his hand and let him trace the groves that made up that panel with his finger-and wow he just sort of lit up and understood what I was describing to him and his day was made from then on. I guess I should have expected that but I have always remembered that experience and your experience Ski, sort of triggered that memory!
