I was taking my car out on a test run around this 10 Mile Loop out where I live. I got down to this Pond Road and this sweaty looking raccoon who was crossing the road going into yard reared up and challenged my car... totally cray-cray... batta-bing batta-boom...
One rainy night I was driving down another country road and it was a gully washer out there. I saw a raccoon ahead carrying a kit, relocating it away from flooding streams... I stopped, she went back across the road several times carrying the rest of her litter to her new spot out of harms way. It was cute... that one wasn’t crazy it was just a mama protecting her babies. I stayed there with the lights on illuminating her trips back and forth. She was hard at work.
In my area there’s a recognized rabies problem with raccoons so you have to be careful.
