Quit inviting the knot heads... we pair up and try to keep the group smaller no more than 6. If bigger than that break it into two or more sub groups based on riding style/ability. We use the Baeofungs with shoulder mics and also Garmin 650's.Since the advent of the shoulder clipped microphone radios we aren't getting much quality riding in. Everyone seems to think they can now go Rogue and disappear at will. Most the day is spent looking for the knothead who is stuck or crashed or upside down. Looking out for oneself seems to have gone by the wayside. I guess the best way to deal with the Rogue riders is to put them on ignore, hope their not dead or dying, then gathering them up at the end of the day on the way back to the truck like the good old days. Technology may make life a little more safe, but on the flipside we used to get a lot more quality riding in when the group made it a point to keep everyone in site.
