I'm planning a weekend tour there in late August. We'll start in Burlington and ride the Island Line rail trail out the causeway, take the ferry across the lake, and then cycle on the islands. We'll have children in a trailer so won't go too far. My only previous experience cycling in the area was a weekend on the islands back in 1980-something. So I can't help you with specifics, but have fun and give us a report when you get back.
Oil is good, grease is better.
