I've only tried it a couple times and so far it does not seem like they have come shallow yet. I haven't tried it in the last week or so since we have had several consecutive days of warm weather though, I'll probably give it a shot this weekend. I took next week off, I'm probably going to try out either Herb Parsons or Glen Springs or maybe both. I found a cove on Glen Springs last spring that was loaded with crappie I've been itching to get back to this year and there is a spot on the levee at Herb Parsons where there's an old road bed where I have worn them out in the early spring in the past. I think when the sun hits the rocks on the levee it warms the water and that draws in early spawners.
