One thing I do want to point out, when riding in a group, try to keep in mind of the experience level that is riding with you, if you know you have new riders with you, you should take some responsibility in ensuring their safety and not putting them in a position to harm themselves. Not blaming anyone here, and I acknowledge the fact that everyone makes their own decisions, but if you have a new rider with you, try to teach and coach them as opposed to showing them how good you ride... just my 2 cents.
