We took the Miller Ferry both because it costs less, was more conveniently located (we came up from Columbus heading west on Route 2), we didn't have to pay for parking, and we got to take our bikes. Not that there's anything wrong with the Jet Express, it just wasn't the best option for our situation.
We had a great time! The weather was about as perfect as you can get, and for the first time, we left the downtown area. I'd never been to the winery before, and I didn't even know there was a beach on the western end of the island! The rocks were pretty harsh on the feet though, so we didn't really make the most of it. We did however, eat more crab and lobster bisque than should be legal.
One question I have though.... we took our bikes to the end of Chapman road (I think that's it) and it basically dead-ended into a house. HOW MUCH FOR THE HOUSE?! It was the perfect setting, lacking only the necessary hammock in the front yard. I want that house!
