Update from my weekend trip to Vegas:
States I actually done something in:
New Jersey
Pennsylvania
New York
Connecticut
Massachusetts
Rhode Island
Vermont
New Hampshire
Maine
Delaware
Virginia
Maryland
Florida
Michigan
Hawaii
Nevada
Arizona (ok, it was only the Hoover Dam side, but it still counts right?)
Total: 17
States I've either driven through or had a layover in an airport:
West Virginia
North Carolina
South Carolina
Georgia
Illinois
California
Total: 6
Almost half (23). I would like to move California from the layover category to the actually did something category.
