I went to so many Schools as a Junior Officer. One was a three week CBR class
Good class and we used a lot of real materials including radioactive materials, that took the starch out of you when you looked at the dose meter at the end.
Thank you for the hazard suits.
We also used real mustard gas but a liquid form which we were required to apply to each wrist. We then used a detox agent to one side…. And got one hell of a nasty blister on the other.
Upshot of this stroll down memory lane is; Moving water! Staying away from the hard ( or muddy and ash shore line) I expect traffic could move from San Francisco to Sacrament and points between with relative safety as soon as they came up with a reason to do so.
A fire Boat and sea water spray as a wash down on both ends of trip ( or even as a scheduled safety procedure) would most likely be an idea some timid person ( like me) would like.
