Kirk "the Minnow" Smith and I played some JEDgolf at Wicker Memorial Park Golf Course on Thursday, December 15th, 2016. It was pretty cold, but it was good to get back on the snow after a pretty snowless winter thus far.
As far as the wind chill? Maybe 10 to 15 below, which makes for perfect JEDgolf conditions. Try it some time... at your own peril.
