RuMr,
Check you elist attitude at the door. It is a public area. There are many better climbs in Leavenworth in locations other than those listed above.
Cragging in easily accessible areas requires some flexibility on everyones part. I am quite sure that a BOEALPS group wouldn't force anyone off of a climb. Yes, they may be waiting for you to finish, but this is true of most crowded cragging areas. If the group already happens to be there, deal with it, and come up with a new plan.
The skills gained in these types of outings protects the lives of those learning them. I am proud that I have taken these courses in order to better ensure the safety of myself and those I climb with. It has allowed me to progress quickly while remaining safe. I also doubt I would still hear complaints when one of us is rescuing you with a system learned on a weekend spent taking "your" climbing space in Leavenworth.
I appreciate the climbing community because it is generally composed of good natured and cooperative personalities. If you would like to join this community, let us know.
