Hooray For GPS Visualizer

Thanks to Adam at GPS Visualizer, here are some awesomely cool toys serious tools for badge flight planning - to wit, circles around Alexandria Airport:
50 kilometer radius circle (silver distance)
150 kilometer radius circle (300km gold distance and diamond goal if a declared O/R flight is made)
300 kilometer radius circle (gold distance)
500 kilometer radius circle (diamond distance)
323.9 mile radius, the current Indiana free distance record

Tool for drawing range rings of any size here and in the sidebar.

For an interesting exercise, locate Sheridan Airport in relation to the 50km circle. Also - try editing the URL with different latitudes and longitudes for the center of the circle.
I should remind everyone that the measurements on these maps are not necessarily the same as the official distances for badge and record claims. The FAI official distance calculator is here.
