Met the raccoon in my backyard. There are lots of raccoons in San Francisco, they live in parks around the city. At night, they roam around, explore all the gardens, looking for easy food in trash bins. They are very good at climbing fences and trees.
Oh, and yes, I am vaccinated against Rabies, so I'm not too afraid of getting close :)
