Ok, I have found a small island on the river that is absolutely lousy with coyotes, even found the den on a high ridge overlooking the sandbar. The problem is that the whole island is nothing but sand so staking of any kind is out. Up in the brush where the den is at a drag would work great, but I want to put some down on the sandbar where they are cruising at night. I thoguht about burrying a cinder block in the sand to run my chain too but it's a pretty long boat ride and I wouldnt be able to take very many. Looking for ideas on a smaller, lighter, stackable alternative.
