Inappropriate Ride Leader
Not all inappropriate riders are newbies nor just riders.
A few years back, I went on a club 30 mile ride with about 20 folks, including a ride leader.
After the ride we ate lunch together - supposedly. Right in the middle of the meal/restaurant, the ride leader started shouting at a lady my wife and I had known 30 years ago and just met again on the ride.
He screamed and yelled at her about something none of us understood. He wouldn't stop. Finally, the 3 of us excused ourselves and went to another restaurant.
Come to find out, he was the PRESIDENT of this very large Denver bike club, name of Rex.
We stopped ridng club rides with this group.
