having been the marshal for the PDGA in Santa Cruz in the past, its all about the dryness and the fire possibilities.
I seriously doubt that the smoking actions can be enforced by the PDGA, and if so, then people will opt out on PDGA events.
Alcohol is one thing as people loose inhibitions and cause actions that are not normal.....not that I havent seen people cause actions for lack of nicotine.....
I don't see this as a PDGA action, but truly a CaliforNIA action to prevent forest fires, and you may have heard of that happening in the past in CaliforNIA.....
