Charlie's Boathouse sits on a grassy, quiet piece of land that's just off the northernmost end of the Burlington bike path. It has a clear view of the Adirondack Mountains across Lake Champlain, and, on a warm May day, the snowy ski trails on Whiteface Mountain were still visible. But at the boathouse, dandelions were in bloom, the grass was lush and the sound of the waves hitting driftwood piled along the shore was peaceful.
