The abutters in Concord think that the trail will hurt the ecosystem by White's Pond. What they really think is that "weird people" will be riding by their homes. They definitely do not want a paved path, which eliminates access for many types of people/sports. It's really crazy to read about this in the local paper. There's a large group of people who really want the trail, but their voices are being drowned out by the negative ones. It's only 3.5 miles! But, it's a moot point because in order to connect the Concord portion to Acton, which will lead into the Westford/Chelmsford part, they have to build a tunnel under Rt. 2! That is supposed to happen in 2010 I think. I hope that really happens, because I actually live closer to West Concord center (where the trail will cross Rt. 2) than Concord center, but I can't ride the closest route, because obviously, I can't ride my bike through the rotary to West Concord. I have to ride through Concord center, across Rt. 62, which is about 5.3 miles, as opposed to 3 miles.
