Cabin, I don't know the DA as my old weather station doesn't give DA However, Napierville Que, is only at 100' above sea level. The track runs West to East and on those early Spring or late Fall days with high barometric pressures, clear, cold days we sometimes have air density ratios of over 100%. It doesn't happen often but when it does, Magic! P.S. a big tail wind doen't hurt either!!!
