Arg!
Sorry to hear that, Rob!
Around here, one has to be especially watchful for speedtraps the last week or so of each month. The state police (and local police) often have mandates to achieve certain "quotas" of citations, and with the town and state governments desperate for more cash, they are pressing the patrols to generate as much revenue as possible.
One ride I frequently drive will often have no more than 1 patrol car for 55 miles of highway, but last week (the end of the month), one night I counted 12 patrol cars - and they had each stopped a vehicle over that same stretch of highway.
