Toll "islands"

[lepidopteran]

Don't forget the Lake Erie islands with regular ferry service for vehicles, namely Middle Bass Island, South Bass Island/Put-in-Bay, and Kelley's Island.

And then there's Cedar Point.  I think they used to charge to get on the inbound causeway, but now the tollbooth is at the other end.  Not sure if that counts, though, since the whole peninsula is essentially an amusement park/resort.
