Lexington, KY has a ton of horse hitching posts/ bike rack posts. That may be because they maintain a fairly decent mounted police division.

there’s a simple reason for that: You can’t leave your horse for hours on a parking spot. You can tie it up somewhere maybe, but not for a long time, there aren’t many places fit for leaving horses nowadays.

This is why you just need to move somewhere with a significant Amish population first. Like, significant enough that local infrastructure plans around them.
