Well, I've made a decision on our next excursion.

We will visit the museum in Bath for a couple hours and then go on one of their River Boat Cruises.

Summer Cruise
Maine Maritime Museum conducts a variety of regularly scheduled river cruises that focus on viewing lighthouses in the area or experiencing the natural setting along the Kennebec River and connecting waterways.
Shipyards & Lighthouses cruise (1 hour)
Daily at 12 pm & 2 pm

See Bath Iron Works, two lighthouses and abundant wildlife.
9:00 AM Meet at HBS
9:15ish Leave HBS
9:30ish Arrive at Maine Maritime Museum
Tour the museum. We will have a docent lead us around some of the outdoor sites for about 40 minutes, then we will have free time to explore on our own. There will be a working blacksmith on site for us to watch and ask questions.
11:15ish Snack
11:45 Meet on dock
12:00 River Cruise
1:00 Go back to cars and drive down the road to....

Virginia

The original ship was made at the Popham Colony back in 1607, and they are building a full size replica in Bath. We will go onsite and get a first hand look at their progress.
1;45ish Drive back to HBS
2:10ish Arrive back at HBS. This may be an awkward time for many to pick up your little ones. Kids are welcome to stay at HBS and play (capture the flag, whatever...) until 4:00 or until their ride comes.
Now for the part that I'm a little wary of... The cost is 15 bucks per child ($6 for children under 6), and 20 dollars for adults. This includes museum admission and the cruise. They are offering us member prices on the adult tickets, which I appreciate. Please don't let money be the reason that your child can't go. I will gladly pay for any child with limited funds. I was trying to figure out a way that would cheaply get us on the water, and while this isn't the least expensive option, it comes with the least amount of possible issues. Boothbay and New Harbor both had tempting cruises at reasonable prices, but longer drives, including getting through Wiscasset, and parking issues, led me to my choice of MMM.
So let me know what you think and if you can go. I'm hoping for another good turn out. Please let me know if you might be able to drive as well. I would expect that we will need two or three others beside myself.
I think this trip fits well with our upcoming study of exploration and colonization. It is also a great opportunity for kids to get on a big boat and see two lighthouses and BIW from the water.
