A few points of interest to share here. From Washington, DC to Delaware Memorial Bridge I counted 12 Maryland State Troopers.
If travelling 95 through Baltimore (either direction) keep an eye out for a dark red Mustang. It's really a Maryland State Trooper. There's also a black SUV (Ford or GM I think) in the same area. I saw both writing people up on my trip.
Laser was in use between exits 4 and 5 on the New Jersey Turnpike (southbound on my trip).
My LPP saved me on 495 in Massachusetts between Haverill and the 495/95 N merge near the coast. The median is very wide with lots of trees to provide cover. The trooper was parked in the brush aiming his gun out the side window through some tree branches. Couldn't make out the gun but I was over PSL when my Cheetah went off! He paid me no mind as I passed him.
That was a perfect ending to an interesting 480 mile drive.
