One thing I can say is that there is too much inconsideration on the trail. Today was crowded as everyone headed to the beach to cool off. The worst riders were the group/club riders. Blocking the entire trail (20+ riders), riding 5 abreast around blind turns, stopping in the middle of the trail (10+) groups.
It's not just the MTB's and beachcruisers that are dangerous and clueless!
