Looks like my description was truncated, so I guess I'll try describing it again here:

1. Adding bridge over McKinstry Brook (mainly based on location in USGS Topographic Maps; it might not be placed perfectly) and updating access rights and road types for this dirt portion of Berry Corner Road to the best of my understanding: East of the brook is public; west of the brook to the Sturbridge town line is private; and the portion in Sturbridge is part of the McKinstry Brook Wildlife Management area and motorized vehicles are prohibited.

2. Correcting where Ayers Road intersects with Berry Corner Road. Based on the signage, and on the numbering of the house at 1 Ayers Road, it should be at the curve itself that the paved road changes from Berry Corner Road to Ayers Road. That is, if one were traveling west from Rte. 169, when one gets to the curve one can choose to continue straight-ish onto the dirt portion of Berry Corner Road, or follow the curve south onto Ayers Road.
