I do not know what happened here but I can probably come very close by guessing. The 12 miles through Maryland on 1-81 have 11 exits and on ramps and I will bet you that some car came off the on-ramp with the attitude, "get out of my way, here I come". When I enter Md. on 1-81, going either way, I move to the left lane and stay there until I go out of Md. Oh, I am sure that I have upset many, many of a driver, because I run the speed limit in the left lane.
