While they are inevitable, I nevertheless grumble when I have to manhandle a gate when leading my horse into or out of a pasture or when riding out to an arena. But I guess that's not practical. The way the gate is hung is often the problem. If it doesn't clear the ground, I may even have to tie up the horse and shove it this way or that. But then, even with my own gates, I griped but didn't do any thing because it called for some drilling and possibly some new post pounding.
Difficulties often lie in the latch.
Many folks use the simple chain and snap clip method. This works, but has several drawbacks. You cannot easily open it from horseback, and when it rains and freezes, the snap clip can freeze shut and often won't budge. Someone, thankfully, has made a horseman-friendly latch. Opening it either from the ground or from horseback is a breeze.
