By the way, for those that haven't, but would like to, you can download the entire Upper Mississippi River Chart book at:

Near the top of the page on the left is a link to download the entire book. Regarding Alton, it is a beautiful marina. Even has a hot tub. Nice place to end up. Enjoy the hot tub and some very nice showers before heading back for the rigs. Also a nice visitor center at the Mel Price Lock and Dam if it's open. And when we got a tour there, everyone found that very interesting. Alton has several good restaurants as well. Dubuque has become somewhat of a partying marina, at least the Dubuque Yacht Basin. It may be noisy on a weekend night. There is a very good restaurant there, Catfish Charlies. However, right next to the River Museum, which I highly recommend worth a visit, is a smaller and quiet marina. That one is behind flood gates named the Port of Dubuque Marina. Not usually a problem in September. The Clinton marina wasn't all that impressive when we held a gathering there. And the slips are perpendicular to the current. Makes for fun docking. There are several interesting towns worth walking thru if time allows. Guttenburg is one of the many. I mentioned the wing dams earlier. They extend out at a slight angle from the shore, and serve the purpose of channeling the river water to help keep the main channel scoured out for the minimum of 9' draft for the tows. They are not always accurately marked in the charts, and usually lie just below the water's surface. If going to a sandy shore to beach for lunch, do it straight in, and slowly. (And be aware of your drift.) I'll admit nothing else on the Mississippi River scares me more than the wing dams. Stay in the main channel between the buoys and they are not a problem. If any of the marinas are in the off channels, be certain of the entrance. There are some narrow channels, some with bends, and if a group of boats have to pass or overtake a tow, it's courteous to give them a call on 13, let them know your intentions and see if they have a preferred side to pass on. Especially if approaching a bend. Tow terminology on the water, on the one, or one whistle means go to right, on the two or two whistle means go to the left. (At least that's how I remember it. For more official wording, you'll have to look it up in regs.

Jim, what are your plans for returning for the rigs? I'm considering another option of launching at Dubuque, as there is a nice park I've used there before. But running upriver to join you guys, and then back up river after arriving in Alton, would probably cost more in boat fuel than sharing a rental and rig gas to make the drive. Colby
