Travel Challenges - Visiting all 50 States of the USA

Since moving to the USA as a British Expat 5 years ago, my wife and I have been doing a fair amount of travelling. Inadvertently, we had collected a fair few images of US state welcome signs! When you're visiting Kansas, North Dakota, Iowa etc one of the notable things on the travel itinerary would be to take a picture of it's welcome sign, and so, the challenge begun!

We still have a few more left! Sometimes when landing in airports, driving to the border can be time-consuming and tedious task, just for a picture! We just have the upper-corners to do and then fill in a couple of blanks! :)

Has anybody done anything similar?
