THE NATION'S railroad and highway systems are the arteries of the nation's economy, and they drive, so to speak, civilization as we know it. Both were built in such a different age, it's hard to imagine any transit networks left to create.

Unless, that is, you own a bike or like to walk, and then you know that a growing system of trails throughout the country -as well as this region - has a similar potential to change life as we know it by connecting communities and cities, with new ways for people to get from points A to B.

The Delaware Valley Regional Planning Commission recognizes this and is trying to give a common identity to the many trail systems here, including the Schuylkill River Trail, the Cooper River Trail and the East Coast Greenway, with a cash-prize contest to name the trail network. Details here.
