Bob, What about the time you posted the trip in your old NT, I think the boat was on some type of track for the lock system. I think it was in Canada. I forget the picture, but it was a few years back.
I had rented a Fountain CC when I got married in St. Thomas in 98. I can't remember the name of the place, but it was in Red Hook in St. Thomas just across from St. John. It is a great place to go boating and very easy to navigate.
I have the Invisible Fence brand and it's the best money I have spent. My golden never leaves the yard and doesn't even need the collar any more. You can get the training when you buy it and it was well worth it. They had to crank mine up at the start, but he is ok now. He can run the whole yard...
