A trail horse should know how to ground tie. Here is Jack shown on a trail ride left standing without being tied to anything. The left rein was dropped to the ground and his rider walked away as a test. Failing the test meant his rider was going to walk back to the truck or be riding double behind someone else. When you ride a lot, there are constantly situations that come up where you need to get off for some reason and there aren’t always good places to tie your horse. You need to be able to drop the reins without concern about your horse running away. It takes practice and repetition, but it is well worth the effort, unless of course, you like hiking!
