That's an interesting list of States, Semiramis.
Most of the biggest, most touristy States are on your list of Not visited.

My husband and I have stayed overnight and played golf in all 50 states. We have stayed overnight and played golf in 8 provinces of Canada and 3 states in Mexico. We are also working on continents and have 5; golf together in 4. We have visited 31 countries. But when they say "see America first", I can say I did! What a beautiful country. My current favorite state is Utah, although ask me in a second and it may be Hawaii or Alaska or California, or... Every state has something beautiful to offer. Don't miss it.

Well we completed our Alaska trip. SO we have been to all the states of the U.S. So we have none left.

I've been to all states except Iowa, Minnesota, Wisconsin, and Oregon. However in 2 weeks time I will be scratching Oregon off the list, as I'm going to Portland. After that I will be left with just 3 states yet to visit. :-)

All but, uhh, uhhh:

Alaska
Alabama
Idaho
N Dakota
S Dakota
Wyoming
Oregon
Nebraska

I'm a 42.

My Mom's been to all 50 bless her little heart!
