2. Hawaii
   Maine

It's no surprise that Alaska is the U.S.'s northernmost and westernmost points, but the easternmost designation might throw some people for a loop. As it turns out, Alaska's Aleutian Islands reach far enough east to make it the easternmost point as well, as they cross into the Eastern Hemisphere.

   Montana
2. Missouri
   Mississippi

Montana's Roe River wouldn't be great for floating since it only flows for about 200 feet. Can't envision how long 200 feet is? Think of it as a little more than half of a city block--seriously.

   Mackinac Bridge
2. Glen Canyon Dam
