I either take the left lane or the left most portion of the single lane as I approach and on-ramp, which (mostly) allows impatient motorists to squeeze by on the right to get on the freeway. The off ramp is a bit trickier...but I can usually watch the flow as I approach and take advantage of gaps...herding motorists if necessary since I obviously have the right-of-way.

"Let us hope our weapons are never needed --but do not forget what the common people knew when they demanded the Bill of Rights: An armed citizenry is the first defense, the best defense, and the final defense against tyranny. If guns are outlawed, only the government will have guns. Only the police, the secret police, the military, the hired servants of our rulers. Only the government -- and a few outlaws. I intend to be among the outlaws" - Edward Abbey
