Well I don't know if its considered public land or not but we do ride on the power line/electric fields behind our barn. There is a path that goes right through them so we ride down it sometimes.
I like trail riding ware i wont be bothered and its quiet and peaceful!! and so does what ever horse im riding!!!!
Over the past years, horses have been excluded from riding on many public land trail systems. One of the ways this has happened is loss of trail heads available for horse trailer parking. Another is exclusion of horses from trails.
