This is not as epic has human car's but here's my trip report for yesterday:

I had decided to condense my most favorite/scenic roads in Baltimore county into one ride that is as short as possible. Basically, a jaunt up to prettyboy via yeoho, prettyboy dam, spooks hill, and back down via beckleysville, brick store, falls, mt caramel... belfast, priceville, western run. Only 38 miles but 3000+ feet climbing.

Here's the bikely link.

Freaking gorgeous.

Except for when I cracked my dropout while mashing up a hill on priceville! I had to very gingerly peddle back to the start point, but it was such good ride it didn't bring me down (it can be fixed).

Now I'm curious, what is your absolute favorite stretch of road in the region? Mine is Spooks Hill.
