There is a lot more information on this map then most people realize. First of all the quad number and name are in each square, the county lines are on it, the State Plane Zones (in faint green) are on it, and the Water Management District boundaries (in faint blue) are on it. I have always kept a plot of my area from this map and posted it on the wall next to me because you never know when you need those bits of info!
