I ride on the road a LOT, especially when the bears get bad up the mountain and on the trails. I haven't got any quiet back roads to ride on, so I find myself riding on the highways along the side of the road.
Good thing Pro isn't at all bothered by the traffic.
Usually I ride so we can see the traffic coming, however if the other side of the road has a larger amount of space I sometimes switch so I have more room.
Sometimes people can be REALLY rude... I've been riding with friends and my instructor and have had people make there trucks go really loud and fast, others have throws things out the window or shouted out, etc. to scare the horses. And the semi drivers that fly by are really bad as well.
A lady who I rode with before said some people in a truck threw a firecracker out the window at them.
It's at the point where sometimes we have to go on the road to MAKE the cars slow down. Everyone who has to ride on the bridges here will go straight down the center, or else cars will come onto the bridge with the horses
. Once we even had a cop behind us as we were doing this and he never said a thing.
Not Fun. But it's better than not riding at all.
I have NEVER been told not to ride on the roads or to move to the correct side, and we have even been up town on the horses. I just kinda do my own thing and if everyone on the road is being respectable I will be as well.
I wouldn't worry about riding on back roads too much though. I'm interested to hear what the actual rules are though!
