Only 10 states remain without a sub 4 minute track mile run on its soil: NH, ME, VT, DE, WV, SD, CO, WY, NV, and HI.
Which state will be the last to see a sub 4?
I think the northeast will get wiped out in the next five years, as will NV. My money is on Wyoming to come in last, but Colorado and Hawaii could put up a good fight for that distinction.
(If I'm wrong about any of these, please correct me. I know someone went for DE this past weekend, but I couldn't find the results).
