Perhaps this is an unrealistic suggestion but it would be a big help to eliminate the gym atmosphere. Chop all the first pitch bolted belays and slings used to top-rope. For example, Son of Easy O has become almost solely a top-rope climb since that convenience anchor was put there. Parties hang their ropes on this climb and many others and leave them there all day trampling the ground below the climb while picnicking. Bring trad-only back to the Gunks.
