I've played every month but Feb, in Green Bay. We usually have one guy carry the hammer for teeing. Although the course we play in deep winter when there is no snow cover, or just mostly filling bunkers, they don't technically allow using the tee boxes. But, sometimes we use them when out of site of the clubhouse, because the tee blocks in the FW suck and render too many of the holes on the course too short. The coolest thing on that particular course is well riprapped pond edges, where when it freezes solid and a ball hits the pure ice, when no snow has accumulated, a neat boi, oi, oi, woi, woi, yoi sound reverberates for a few moments. A few years ago, some dope hit his ball out thirty feet or more on the ice and inched his way out with his water ball retreiver, and when he got about 10ft off shore, went though the ice in about 3-4ft of water...
A few years ago, we had an unusually warm spell through Dec., and it was quite a physical stress playing golf in the day, and curling in league at night, and go back to golf the next day. This is one place I suspected I screwed up my back for several years with too much stress on back muscles. Hitting irons hard off frozen turf has a bad cumulative effect...
