its pretty poor most of the way along. Runners seem unable to stop and cause more problems/dangers then anyone. I happily wait at he end of a tunnel for "traffic" to come the other way, where-as runners just barge their way through even if your 3/4 of the way through which is a inconvienince for everyone.
but i do like this clip as the girl coming down is just unaware and in her own little world of flowers and bunnies.
