This summer, junior Grace Butler received a Psi Upsilon Environmental Fellowship from Bowdoin to intern with the Bicycle Coalition of Maine, an advocacy organization based in Portland. Butler, a sociology and environmental studies major, took on the task of completing an economic benefit analysis of bicycling in Maine. She surveyed the businesses, big and small, that support the bicycle economy here, consulting with economists along the way, to assess how much money bicyclists contribute to the state.
