I've always wanted to do that! What's it like riding beside the highway? Scary? Do people honk and stuff? The closest places from me are 5-10 miles away..but not on busy roads. How long do you think it would take?
Is there anything illegal about riding a horse on or near a road cars use?
Around here, it's illegal to ride on the interstates, but nothing wrong with riding on other roads. I try to limit how much I do it simply cause it's not any fun at all.
