Kendi, I don't hate commercials, and I am a private boater. Like anything else, as long as your smart about what you are doing, no reason to hate anyone on the river really. We're all there for the same reason!
As for peeling out into your group, of course that's bad form. But I would say it's bad form to pull out into the middle of any group, commercial or private, regardless of weather you're a private boater or a guide. Some people are just dicks though. I suppose there is a chance they didn't realize it, but more than likely, it was all about them.
As for the ramp, no excuse for that. It's one thing to be taking your time on the ramp and be in everyone else's way, maybe not realizing it even. But if someone asks nicely to make room, then people should have the courtesy to make room.
Second thread this week on people just being dicks. There must be more than one dick in this world... LOL
