Only Eleven States to Go!

After today, I will have only eleven contiguous states to drive a semi-truck into. I am currently in Massachusetts and will be driving into New Hampshire today. If you count Alaska, then I have twelve states within the North American continent that I have not driven into.

The remaining states that are in white in the map on the right which I have not driven into are:

Alaska
Arizona
Idaho
Maine
Montana
New Mexico
North Dakota
Oregon
Rhode Island
South Dakota
Vermont
Washington
