I got what might be a tropo hotspot for y'all...
Back in the 1990's in the Summer, I used to ride through the Nevada, Missouri area with my family going to see cousins who lived up near Kansas City. It may just be some kind of fluke or something, but just about everytime near the Nevada area, we'd get Little Rock, Arkansas stations on the FM radio in the car! I'm pretty sure that LR is at least 300+ miles from Nevada. I live near the Arkansas border and certainly don't get any LR here, ever.
I haven't been back to Nevada since then, so I don't know how consistent it is or if them times were just freak occurances, but back then, it sure struck me as plumb weird/awesome! I'll never forget it.
