Red, I detect that somewhere deep inside there lurks an evil...
Pool Noodles in a breeze should dance like snakes. So, if the horses eventually stop worrying about snakes, what happens when we're out riding and come upon a rattler?
Everyone I know out here trains their own horses and many do their own shoes too (ours wear no shoes because we seldom take them anywhere that isn't relatively soft). Maybe those who live in the suburbs of the "big city" (as if anyone reading this would consider 70,000 population as big) and have an ego horse could use your services, but that doesn't seem like a very profitable business here. How are ya at driving cutters, balers, or even semi trucks?
Fuzzy
Desensitizing doesn't stop a horse from justified flight reaction... What it does is accustom then to thought over reaction, so say your on a trail and they catch sight of a snake like shape on the ground that isn't a snake.... They won't just immediately jump and or bolt, but look at the item and recognize it as no threat. Also, pool noodles are stiff.....so not very snake like
As far as driving large equipment, I don't currently hold a class A license, but I'm thinking about moving into that field. I used to drive a crash rescue truck that was larger then most semi rigs
That second vehicle is far larger then the first, though its hard to tell just how much in the pics
