The title says it all, pretty much, but here's the long version:
Me and my friend like trail riding just for fun, and we do like, small picnics sometimes. We want our horses to enjoy themselves too, so we are trying to figure out how to go about grazing them. The first time, we held the horse's leads while we ate, but they kept on bothering us. The second time, we put baling twine on some trees and tied the horses to it, but we wanted the lead ropes tied long enough that the horses could graze, but not get their feet stuck. Neither of us could find a way to accomplish this, so the horses could kind of graze, but not much. We ended up not being able to just relax, because we kept looking at/checking on our horses to see if they were ok, happy, and we felt bad for them since they couldn't really do anything but sit and wait.
How to you guys recommend tying on our picnic rides? We have heard of picket lines, how to those work? We can't really afford anything expensive, we are teens, and have to pay for a lot of our extra equipment out of our own money, our parents just pay for the lease on our horses.
To cap it up: We need an inexpensive, efficient solution that works for the situation I described. Recommendations and examples of how you guys tie on trials/picnics when needed would be great, thanks in advance!
