There's this one particular area on one of the back roads I frequent where there is some form of small ground-squirrel colony. There must be a hundred or more of them. I was riding past one day, and all at once there was 20-40 of them all dashing across the road simultaneously, right in front of me. I was able to stop just in time, but at one point I thought some of them were going to be running right across my toes. Cute little buggers, but I'd just as soon have them stay on the side of the road.
