Help us complete the City of Cohasset match. If $150,000 in local dollars are raised, then Cohasset will contribute $300,000 to the project. We are very close to starting construction and have a budget with plans for these funds to create amazing trails. If you plan to ride or are going to benefit from the economic boost brought by the trails, please contribute!
