+1. I used to lead club rides. On cooler mornings people would dress to be warm in the parking lot while waiting for the ride to start. I took to walking around telling people things like "You are not going to need that jacket. We are going to start climbing after the first 2 miles and it's going to warm up not that long from now." Sometimes there would be people who wouldn't listen. 20 minutes into the ride they are needing to stop, shed layers and figure out how to carry them.
