It was a great feeling when I finished swimming across the Mississippi River, to fulfill my to-do-list-before-I-die. Even though it was at the Headwaters, MN, where the Mississippi River is only about 30 feet wide, but of course I did "Swim across the Mississippi River" (check).
The Mississippi Headwaters is located in the Itasca State Park under the Minnesota Dept. of Natural Resources. There is a wooden sign to signify the headwaters,
HERE 1475 FT ABOVE THE OCEAN THE MIGHTY MISSISSIPPI BEGINS TO FLOW ON ITS WINDING WAY 2552 MILES TO THE GULF OF MEXICO.
"Mississippi" is way harder to spell than "Amazon" or "Nile". LOL.
