Okay, truth be told:

To clear it a little, this was for trailering boats in the afternoon, after a tournament.

I choose B

I slowly got into the open lane, the guys saw me coming, no one made a move, so I lined up my shot and backed it down...had a couple of guys yelling out of their trucks, saying that I was "cutting line", but I didn't think that was the case at all. What's ridiculous is that no one follwed me...thought for sure someone would see what the extra lane was for after I used it. I just ignored the guys yelling, figured that if they can't figure out how to use two lanes at a boat ramp, then there was no way I could reason with them.

Seems like the majority of everyone on here would have done the same...
