Quietly, COSS Inc. has been creating what we hope will be the premier open space information source in town. It has an extensive blog section covering our continuing posts about people, sites, history, and events from around Chelmsford. The site can be searched by any AI engine, so it is a solid and growing source for local open space information. Maps and trail maps are in the final stages of being rolled out, along with information on all open spaces in town. Some of these maps are being corrected directly on OpenStreetMap, which means you can download current maps to your phone, something many local websites cannot offer because their maps are out of date. Take some time to read a few of the stories below, and check it out at www.ChelmsfordOSS.org
Below is the current full list of blog posts across all blog pages on the COSS website.
