I find it helps to go exploring...pick an area, and then take all the little roads I haven't done before.

Sometimes I go house-scouting...I'll keep an eye open for all the houses for sale and check them out.

Today, the thing that kept it from being boring was that I was climbing at only about 4.5 mph, and I had lots of time to look into the beautiful forests and at the mountain vistas while I rode! LOL
