Hmmm... I never thought about it before.... does that mean I don't mind it?
One trail we ride is different each way. One way is all uphill, the way back is down hill which is a lot of fun to ride. It goes through a park, behind homes with horses, and along a mountain range with snow (in winter). I don't mind that at all.
Another route is high traffic and I prefer going another route back only because there really isn't anything interesting along this route to make me want to see it twice.
