That's what we do. The only thing is they don't show up all that well so I don't know how much that helps. What we did is just carried a little shovel and I'd take off a chunk of dirt and push the keel into the dirt. Next year my friend I hunt with said we should buy a couple dozen of cheap tanglefree waterdecoys, cut the keel off and drive stakes into them turning them into field decoys because actual field decoys are so expensive.
