29 States!

We have a map on the side of our trailer with stick-on vinyl states, and we add a state once we have set foot in it with our RV. Here is the map as it stands today, reflecting our 2-1/2 years of RV travels.

 

I have to confess that we cheated with Michigan.  We were driving across I-80 and were so close to Michigan that we took a 10 minute detour and crossed the border.  But mostly we've been legitimate visitors to all these states and have camped overnight in 20 of them. #1 is Florida, with well over 200 nights and #2 is Tennesee, where we've spent about 60 nights.
