So, Layton, if you walked up to...say...the NE Ridge of Bugaboo Spire, and there were more than three people on the route, you'd get pissed off and go home?
I think you know the difference between a mass of people sieging a route together and a bunch of separate parties converging via a coincidence The difference lies in the responsibility a "party" has to its members. The larger the group the greater the responsibility/management gong show.
