If you start to feel cold over the weekend, think of Don Skog and the folks at River Haus Bait Shop in Fond du Lac, Wisconsin. "It's 5 below zero," Don said, "and the ice on Lake Winnebago is 20 inches thick." Still, Don says that die hards are heading out on the ice to catch good numbers of bluegill and crappies. Don points anglers to Green Lake, which is over 100 feet deep. Don explains that the deep water keeps the water warmer and the fish more active. Guys who are camping out on the ice and jigging red and white spikes and wigglers are catching good numbers of big panfish. Don suggests guys check out the wind-tips, which bob use the wind to bob a jig up and down. "It's going to warm up to the 20s this weekend," he said, "so there will be a lot of people fishing on the ice."
