Out in the trail we have often needed to ride over a metal culvert. Our horses don’t even slow down and look at them anymore. But the first time can be worrisome to them. So, we have this piece of metal corrugated roofing that we buried partially in the sand to imitate a culvert. I started it yesterday and ended a long session once he put a foot on it and walked across a corner. I was happy for his try and he could then think about it for the night. He walked over it tonight the second attempt.
