If this was a group of seasoned riders who understood what they were getting into to I wouldn't question it. But your description sounds like a no-nothing manager is proposing something he doesn't have a clue about. Is that correct? If so, advise your son in law to train or decline and then stay the heck out of it. What benefit is there in inserting yourself into some nut-job's management fiasco? Don't you risk causing harm to your son in law's standing at the firm?
