Rain will drain through those piles of snow, so Macker, explains. Rain passes through man-made snow. Some will be lost, but as the temperature drops tomorrow, Macker will start grooming tomorrow night and then early friday morning. He's said I can ride with him. That would be at 5 am on the groomer, so I will be taking an, ahem, raincheck... The piles of snow will get ground up into frozen granular. Lake effect snow is in the forecast, and best of all he says, he who is painfully honest with me about these things: "Natural snow ground with man made makes for an awesome ski surface." Then he said that line "We are just snow farmers." And, like farming that means subject to the weather. However he's used last weekend well farming the powder, and I plan on being there early on Saturday. But not at 5 am.
