I am taking a 10 day vacation starting next week. I would like to take a break from all the hunting I have been doing and go for my first real wintertime crappie trip. I would like to know what technique I should use. Slow trolling, vertical jigging, spider rigging etc. Approx water depths I should look for. And which lake is typically a good producing crappie this time of year. I am clueless about winter fishing, assume I know nothing. Thanx in advance for any help!
