Caught two keepers yesterday drifting in the wind not too far from the shore. Just had a small jig tipped with a live minnow while throwing another line for bass, I wasn't even trying hard to catch crappie. If you really get into them you can catch a lot of them. The lake I fished, they cut down trees all the way around the lake to provide cover for crappie in the spring. You can probably find similar things or even submerged Christmas trees on many lakes. Also man made fish attractors which are often marked with a pole or buoy in the water.
If you're not drifting or slow trolling, a crappie jig under a bobber works good too, even without a minnow. Enough wind to make a "crappie ripple" on the surface will keep the bobber moving and bounce the jig around so you just let it sit and wait for a bite.
