Last weekend we went to the SF Zoo. It was raining/pouring, so we were skeptical. It turns out that going to the zoo on a rainy day is great! There was no one there. We've never seen the grizzlies so close. It turns out they really like kids. When DT came up to the glass, they came and sat right next to him. We didn't even bring a camera, so we had to resort to camera phone. Not too bad.
They also had this ball that they could shake to get treats out of. They sure liked it!
