spaz, i've read the same stuff.
Either way, rabies carriers or not, I just plain don't like 'em whether it's rational or not.
Have you ever gotten close to one and seen that hissing, spitting, drooling and tooth display thing they do?
Sure, maybe this is just a "possum bluff." Who cares? I tend to call their bluff with a little lead if they don't beat a hasty retreat.
Maybe they don't carry or transmit rabies. But they eat offal and I bet a bite or scratches from one could result in a nasty infection for humans or pets if not properly treated.
