wildebeests

Driving back from Wild Waves with Nathan and his friends today, I looked down at the speedometer and was surprised to see we were going over 70 mph, at least 10mph over the speed limit. There was a bunch of us in a pack, 20 or 30 vehicles.
I thought to myself "how does a State Patrol officer choose which vehicle to pull over and ticket?"
Maybe it's like a lion watching a bunch of wildebeests moving across the plains of Africa.
"Typically the predators attempt to cut out a young or ill animal and attack without having to worry about the herd" - from Wikipedia
I was sort of in the middle of the pack, so I didn't worry too much, and I just watched for tail lights further ahead.
