My Evening Loop

Luckily they're all pinecones

So it's early evening on a weekday, and I can still hear the phone ringing in my ears.  I've got about two hours of daylight left and a mountain biking itch to scratch.  Where can I go to find a little piece of heaven?

The Middlesex Fells are close, but there's a lot of "forest service road".  The trails have a few technical spots, and the hills will get you in shape pretty quickly.  However, there is only one loop for mountain bikers.  I treat it like my time trial course: where I go to gauge the progress in my conditioning.  That is to say I like to avoid it because it reminds me what a fat wheezy creampuff I really am.
