I'm beginning to think there is something about the Merrimack River and its tributary, the Concord, that induces people to behave strangely. I can't believe how many stories there are every year about people jumping off bridges to avoid police around here.
A clear sign of lack of sobriety is jumping into the Merrimack to avoid a sobriety checkpoint:

Even weirder than jumping off a bridge to avoid a sobriety checkpoint is jumping off a bridge to avoid being pulled over for running a stop sign: http://www.thesunblog.com/policeblog/archives/2010/12/really-bad-idea.html -- not a good idea at all.
