Madman,
No worries! There won't really be any set-up.
I'll still use you if you dont mind, as a team leader if not enough come at 8:00am. I just need a guy that can lead other folks up the road to a certain clean up spot (they'll be marked by number) and hand out bags, water etc. Just call on the radio if there is a problem etc.
Go ahead with your guys at the meet up location.
