It's gotta be the climate. There is no other explanation I can think of.
Thanks - very interesting. I’m surprised our rate is that low.
So, what would be the difference, say, between Utah at 1.7 and New Mexico at 6? Oklahoma also surprises me at 5.1, and what’s going on in Lousianna?! And D.C. is almost up there with Mexico!
Could you give the URL to the pic? (my device doesn’t tell me) Thanks.
