Kemp St. to Dan Parker to Martin's Pond

Dirt route from Kemp St to Rocky Hill Rd, Groton, Middlesex County, Massachusetts

"Mix of road types. Kemp St. goes from pavement to gravel/dirt. Dan Parker is rideable double-track at times and very rough for skinny tires in other spots (like a logging road -- big ruts and tire tracks that make it hard with 32mm tires like mine). This route includes a trail/single track bit that is a little sandy but mostly rideable and actually much smoother to bike than the wider Dan Parker Rd."
