Hi,
Wow it's been a long time since i heard a good possum story. Over 30 years ago i took pics of one at the bottom of the garbage can in New Jersey. Here they dont seem too aggressive they just run away. They do look like they can inflict quite a bit of damage to the skin with those dang teeth dont they.
A while back we had a large skunk out at the garbage can here where i live now. He seems to have gone away now though. He too was in the bottom of the can and i (carefully) took pics of him too. Very sharp looking animals.
Back where i used to live way back then we had all kinds of stuff wander into our yard. Horses, goats, rabbits, skunks, possums, moles, squirrels, chipmunks, huge birds, you name it. Here i have seen one mole and one skunk and some squirrels and rabbits.
We do have to be careful here now though as bear seem to be migrating as they look for other sources of food. They end up in peoples back yards sometimes.
We also have a big problem with deer as they like to cross highways and other roads in this area. People hit them on an almost regular basis.
