It also seems to be more common to see raccoons crossing the drive,on the north side of the Great HIll, where bikes are climbing, than on the south where they're going faster.... except near the bottom where they can see you coming.
There's one big old arrogant raccoon who lives in a tree near Lasker Pool/Rink who doesn't seem to care. I've passed him a number of times, paused in the middle of the road, licking some snack off his paws.
