(Apologies for hiking hijacking the thread, but I need to complain about the geese)
I grew up in the Boston area. When I was younger, there weren't too many Canada geese around, but by the time I left after graduating high school, they were basically everywhere all year round. I'm guessing that they've come even further south than that now (if they hadn't already). Given the amount of faeces in basically any sizeable open grassy area in the town I grew up, it seemed pretty clear they weren't just visiting any more.
