I have certainly jumped the gun a time or two this time of year. I'll get out there early in the year, get all fired up because the weather hits 60 degrees one day, and catch one 8" bass... I look for one or two stable stretches of weather before I get out for LM. I look for air temp lows above 40 degrees as well. 3 or 4 days were the lows are above 40 and it's on! The last full week of March this year should be good. If the air temps cooperate it will coincide with the right moon phase. I can't wait!!!
