Anyone happen to know what the current (march 3, 2016) frost situation is here in Minnesota around the Anoka area? I need to start pounding posts as soon as the frost is out of the ground. Driving the tractor the other day I was cutting in to the ground about 6 inches (sloppy, loose, muddy). Its been colder the last couple of days and I don't know what the frost might be like deeper in the ground as opposed to what I see at the surface here. Just thought I'd ask on the off-chance anyone here might happen to know the situation.
