Huh. I thought SAG meant 'Stop And Go', like the truck would stop, pick you up, and you would go. Duh. But yeah, on organized bike rides, they are kind of nice to have, especially if you don't know how to fix a flat. I got a flat and had to ride in the SAG once - now, I always have a spare tube.
I ride a couple of charity bike rides/tours a year; it is just bike nerd fun, like a TrekCon for SciFi nerds (which I am also).
