You awaken from sleep - something has disturbed your peaceful rest in the hammock. You listen. You can see nothing in the darkness. Hmmm. As you roll over to go back to sleep, you inadvertently trap three bats in the netting of the hammock. They have been quietly feasting on your fleshy feet. You've lost a pint of blood, but these critters will be making a new home at the Brookfield Zoo.
