Something amazing about our bike shop is that despite our urbane location, we have a huge interest of mixed-terrain and off-road cycling on staff. What’s even more amazing is that Boston is a great city to be in for this kind of riding.  I took a rental-car escape the other day to get out of town and back in the woods and ended up at Pawtuckaway State Park in southern NH – less than an hour and a half from Cambridge.  It was a freak 70-degree day, blasting over a four-inch thick carpet of dry leaves on NEMBA-carved trails to the soundtrack of muzzle-loaders in the distance.  We’ve got trails like these a lot closer to home, but it’s always nice to explore what’s beyond your backyard.
