What a week to visit Rumney, Ward. Way to go. Hope everyone had fun.
I should not be saying this but here goes - if the parking lots are overflowing with cars, just walk a little further, be ready not to visit the most popular crags, and be a little flexible about what to climb or the order you do the climbs in. IMO, certainly no worse than The Trapps and Near Trapps at The Gunks.
