I also suggest redo'ing the list. Give a one or two week period where people on the list resign-up again, and anyone wanting to be added to the list, gets added. Everyone keeps their original place in line as in the first list, but anyone that doesn't sign up, loses their place. This way Henry doesn't spend 3 weeks at someone's house while they waste time trying to contact the next person for their address. We'll rid of the inactive people that signed up 2+ years ago, while Henry will travel to the active CC members.
