Trocadile

If somebody doesn't beat me to it, I'll go back and take more pictures and note more details. If you look at Google Maps you can see the trail as a grey line. I accessed it by taking the first right off Concord Rd., coming from Rte. 20 (don't think the road had a name). I traveled west and tootled along for about three miles. I passed a rough parking area, maybe at Plain Rd. (?), and the paved portion continued on, getting close to Wayland Center. Coming back the other way, I passed where I joined near Concord Rd. and continued east to where the trail is interrupted by the raised Conant Road. I did the cyclo-cross thing up a dirt trail and saw that there was more paved trail on the other side, heading toward Church St. According to this: https://patch.com/massachusetts/west...t-construction, work will begin this week to open the underpass, and the path continues east to the Waltham line. I didn't have time to sample the trail east of Conant, but it sounds like it's paved through Weston. According to this: https://waltham.wickedlocal.com/news...ide-rail-trail, Waltham may begin construction sometime this year on it's portion, which, as you suggest, would be huge for access to the west. The article mentions 1265 Main St. to Beaver as the route, which would effectively bypass the worst of Waltham Center.

edit: just read one of the links provided by Rod and it may be that the rough parking I passed was at Warren Ave./Gun Club Lane.
