Mississippi River

We cross the Mississippi River on this bridge on our way to Ft. Madison. On our way back we have to pay $1.00 to cross. This is a moving bridge, it splits in half and opens up to let the tugs go through. During the summer this happens quit often, the tugs push 15 barges caring coal and corn which holds the equivalent of 870 semi's, there are no weight limits on the river. It is very interesting to see this happen, but delays our grocery shopping up to a 1/2 hr. sometimes.
