The first time I saw an opossum, loping along at dusk in the vegetation at Fort Tilden (it, not me, though actually it was both of us), I had just come back from Tuscany, and I thought it was a wild boar. It paused and looked back at me. I do not think it thought I was a Tuscan boar hunter. I have since viewed possums a number of times at their condominium in Rockaway. Once, after a party (ours, not theirs, although we can't know that for sure), a possum sat on the roof of a bungalow receiving slices of Wonder Bread tossed up by my neighbor. Last weekend, the possum population reached critical mass. Here is a link to Night of the Opossum.
