RT I don't think its not that they don't know better.
They just don't care.
They're the ones people remember and give all the rest a bad name.
I know many great guides and have guided myself.
I also have encountered some pretty rude guides on the river.
Many of thgose are the local hero in Vt or M****s that really have limited knowledge so when they bring a group from home in they are one trick ponies under pressure to giterdone and aren't going to let manners get in the way.
They have told there clients this is how it is on the SR and they don't know any better.
