I’ve a dead animal in my garage; the smell is unmistakable. I’ve a tangle of bike wheels and frames on two walls, other gear on the third. Two years ago, a large opossum got tangled in them and died. I had to pull things away from around the carcass, shovel it into a garbage bag and then double and triple bag it, and then treat and clean the floor, setting up an exhaust fan and running it for days. About twenty pounds, just enough to be awkward, making an “arms length transaction” impossible, maggots of course. I haven’t found it this time, but I’ve got my work cut out for me.
