I pose a question to those who don’t like the idea of corking and/or just share a common disdain for Critical Mass in general. Have you ever considered how much traffic a really large group of cyclists could back up if they didn’t cork intersections? I’m estimating they can possibly back traffic up for close to an hour in some areas, not just a few minutes as they presently do. That is, obeying all traffic laws, riding two abreast, stopping at red lights, no corking etc. Chew on that for a bit.
