@Chris — you broke the rules. This thread was supposed to be apolitical.
I think @gorudy was opening up a can of worms when he started this thread.
Seriously though, I found Chris’s share fascinating and he broadened the discussion to “What exactly do we mean by a wall?”
What about the loss of tourism, outdoor art and summer-under-the-stars film screenings?
On the other hand, I think the ability to identify animals could be beneficial to ranchers in tracking down runaway cattle or getting an alert to an approaching wolf or other cattle predator.
Could the government provide an animal only feed to ranchers if a virtual wall was implemented?
