Being from Kansas City and having family in rural Kansas made this one fairly easy for me, because the locations in Kansas and Missouri (and lack of locations elsewhere) make it pretty obvious.
Well, pretty obvious as to the overall theme. I figured out the blue dots first, and it took me a minute to figure out the specificity of the red dots. For example, I was expecting a red dot in central Arkansas at first, but then I figured out why there isn't a red dot there (and why there isn't a red dot that corresponds to the Arkansas blue dot yet).
I think Gina would have a little harder time with this one since there aren't any with any ties to the PNW, so there's no hometown connection to see. I'm pretty impressed that a teenager from BC can get this one on the first day!
Maybe I've got it wrong then.... I guess I'll wait and see. One question should answer it - are there 45 dots?
I didn't count them all, but there should be 82 total dots, 44 blue and 38 red. The fact that you asked about 45 tells me that you're on the right track, and that you probably already figured out the blue ones.
If I've figured it out correctly then the red dot in Kansas showed up in 1969 and the last red dot to be added to the map was in 2006 in Michigan.
Means blue dots is what I thought both sets of dots were.
I was confused about 44 vs 45 for the blue dots, but just learned something new thanks to google. I had no idea about that little bit of history, or the interesting numbering scheme.
Back to Biochemistry now... unless I need to revise again :)
You got it!
It's hard to believe it's been 12 years since the last red dot. But looking at the list, there were recently spans of 21 years (1973-1994) and also 18 years (1945-1963, which interestingly both were still in office when those dots were added). Longest span between red dots was 26 years, which was between the first dot and the second/third dots, which were added on the same day!
