I ride to work on one route and home on another. It's only 1/2 as boring that way.

Actually, I think it's good to repeat the same route. You get a good feel for traffic and know the best way to deal with hazardous areas. When something is out of place, it raises a red flag quickly. You also get to know the roadside trash and roadkill by name. ie Billy Bolt, Squishy the Squirrel etc etc.

[ BTW, I would like to thank the guy that posted about naming the roadside stuff you pass on the daily ride. It has led to a new level personal psychosis. ]

Commuting rides are one thing, but on rec rides the mystery destination and route rule the agenda.
