G'day folks,
When I was a kid in Cobram, I had a brushtail possum problem!
The buggers would jump out of a tree, and land on the tin roof above my bedroom with a loud thump, then scuttle across the roof, and jump into another tree, on the opposite side of the house.
Even shooting them with a .177 air rifle didn't successfully discourage them; only cutting down their launch tree did that...
Meanwhile, a how-to on prep and cooking of North American possums:
From a book on North American wild foods. And the recipe above that one is for Porcupine!
