I'm moving to Nebraska in January, so I'll be embarking on driving every mile of state highway in my 3rd of 50 states- Nebraska!
Wow, great job! How many miles have you driven for this project?
Within Wyoming I'd ballpark about 20,000. My car had 40,000 on it when I got here, now it has 70,000, and I put at least 5,000 on rental cars just within Wyoming. The 30,000 on my car also includes a few long roadtrips outside of Wyoming and day-to-day driving, so probably 20 total.
The system is about 7,500 if I'm not mistaken, so 20,000 isn't horrible given that there was a lot of doubling back and I didn't do it in one fell swoop (I drove WYO 487 at least 7 times, for instance). If I did it all at once I probably could have done it in half that many miles.
