Davo, seeing 12 cops doing speed checks on a long trip in the Northeast is not unusual. I had 4 speed traps while on my 25 mile commute to work on Monday. In the Philly area, the top speed limit on the highways is a measly 55mph while most of Nebraska is 75. The cops love to enforce it. Try driving 55 on a highway in Nebraska and those crazy truckers will run you off the road.
I drove from Philly to Denver and on that trip I encounted like 5 speed traps on the PA Turnpike ( speed limit heavily enforced at 65mph) and a couple in Ohio. I didn't see one cop in Illinois, Indiana, Iowa, Nebraska or Colorado.
