We have only been to about 30 states, but stop at the "Welcome to.." sign, if we have a picture of this sign, we have been to this state. Some took several trips to get, Arkansas has a sign on the I40 bridge over the Mississippi River, while we had to climb a hill to get a legible picture of the New Hampshire sign. I try to get the kids in the picture, helps pinpoint the year. Now that they are older, they just roll over, yawn and refuse to budge, their loss.

I'm still working on my total, however, my brother not only has his 50 states, but also all the continents! He is currently in/on Antarctica!
