They come out at night on the sand and even dry land, at least the rusties. I have found them in my pasture many time, 50 yards from the creek. We have walked with flashlights at night and scouped up lots with a net. They come right up to dry land and on it. If you ever by the rv park at the dunes on moses, go there at night and walk the shore. It will amaze you how many there are. Picking up 80 to 100 is an average night in a couple hours. My guess it would be good in lots of other locations as well. It just cant be to rocky or you cant scoup them up.
