Went out yesterday for a couple of hours.  Ice thickness where I was is between 7-8 inches.  There was about a couple of inches of crusty ice on top, but solid underneath.  Looks like most of the slush has frozen up in the areas where I was walking.  There were a few 4-wheelers and snowmobiles moving on the lake as well, so some guys are feeling pretty confident about the ice.  I fished deep, about 45 ft of water, marked some suspended fish, immediately got hold of a nice crappie that I lost at the hole.  Marked a few more but couldn't get them to bite after that.  Others were reporting a catch of descent crappie in about 30 ft of water.
