Network issues (linked to Focus Colors of PARI ?)

I had a good Focus ride on Friday, but didn’t notice how many riders were on that iteration of the event. Yesterday’s, with nearly 3000 riders, was a disaster. More discussions including here: Mass start events - #3 by David_Rossall

In a way, the ride was amusing. Bikes with no riders going down the road. People, and riderless bikes, going in random directions. At one point I was just my hair, nothing else. And then a load of tail lights not attached to anything, like a set of fairy lights floating down the road. Quite pretty in a way…
