For a fun, challenging drive, my commute from I-84 every day is a great test if you like lots of hills and turns..provided it's not snowing. I-84 East, take exit 73 in Union. Head East on 190 to 171 East. This will take you through wonderful Bigelow Hollow State Park and the Yale Forest, a beautiful, up-and-down ride. At the fork, take 197 East. This will take you to Woodstock. Follow it to Rt 169 South (far fewer hills and curves), and head down to Lisbon on this National Scenic Highway.

edit: Someone else mentioned Yale Forest!
