Traveling

I'm packing my bags and leaving on a plane tomorrow morning.  Where am I going???

I'm going to Colorado for the weekend to visit my brother.  I've never been there and am pretty stoked about my trip.  It will be short - Friday through Monday - and I'll be running in the mountains.  

After my trip is done, it will mean that I have traveled to 22 of the 50 states and Washington, D.C.  I've been to:

1. California
2. Colorado
3. Georgia
4. Illinois
5. Indiana
6. Iowa
7. Kansas
8. Kentucky
9. Maryland
10. Michigan
11. Minnesota
12. Mississippi
13. Missouri
14. Montana
15. North Dakota
16. Ohio
17. Pennsylvania
18. South Dakota
19. Tennessee
20. Virginia
21. Washington
22. (Washington, D.C.)
23. Wisconsin

Can other people still recite all of the states in alphabetical order?  "Fifty, nifty United States from 13 original colonies..."
