[BC] FM bays, slight drift

[Tom Bosscher]

OK,
    This has little to do with whether to go with 1 bay or 16, but about 
the curvature of the earth...

    Assuming the earth as a round ball, ( I know it isn't a perfect 
ball), and assuming Kansas type dead flat land, just how much does the 
earth "drop" after 1 mile? I know I should know this, and it probably is 
high school math, but I'm just a curious and lazy kind of guy...
