I stopped attending Cascade rides not because of the mass of people but because the behavior that I saw seems to have gotten worse in the last few years (or maybe that's just my perception). People riding 3-4 across not sharing the road, litter, flipping off motorists, just generally bad behavior I did not care to be around. Chilly Hilly is probably the most "chill" of all the Cascade rides and probably the only one I would still consider doing if I were still doing group rides.
