In addition, this weekend is the "Air, Land, and Speed" (I did not make that up) campaign by the VA State Police to crack down on speeding and to severely enforce the speed limits on major interstates. I saw ~6 Troopers between Roanoke and Blacksburg (when on an average day I see only 1-2) this morning on I-81. Which comes as no surprise, people regularly do 10-15 mph over the posted speed limit on I-81. However, in order to not get run over you have to go with the flow of traffic and do 5-10 over the limit. The only problems I see are when yahoos (8 times out of 10 from out-of-state) driving very aggressively, swerving in and out of lanes, using no signal, and tailgating; which just makes it more dangerous than it has to be.
