It is illegal to tie your horse to a parking meter.

The Law Explained

In Tarentum, if you ride your horse into town, you are strictly prohibited from hitching the animal to a coin-operated parking meter. When automobiles first began replacing horses, parking meters were newly installed to manage cars, and confused riders used them as convenient hitching posts. The town quickly banned the practice to keep large animals off the sidewalks and prevent damage to the new municipal equipment.
