Why was the distance for both NASCAR races at Pocono, Pennsylvania shortened to 400 miles and 160 laps?

MHZ is not a unit of measurement for Distance. MHZ is Mega Hertz which is a unit of measurement for FREQUENCY. If your asking how far will those Radio Frequencies go > Line of Site.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
