Yeah, this whole area used to be "small rural/suburban towns," but that is changing (and has been changing for the past 20 years.) We can either stick our heads in the sand or be smart about it. Littleton has plenty of potential for growth without losing its rural charm (eg, Springdell Farm was just permitted to expand their composting operations, which will allow them to keep the farm.)

The best locations for growth are hubs like 119/495 and 110/495: easy on/off access to 495, most amenities are already right there (groceries, restaurants, offices, etc.) Adding a public transit/bus line option along 110 decreases traffic. Linking to the commuter rail further decreases traffic. Want less traffic? Build a robust public transit system.
