We just emailed a team captian of a team and they replied and so they will move us to the team. The team captain can contact the bike ride person (I think there is a Team coordiantor)...and the ywilll "move you over".
I willl now be part of the Texas Children's Hosp team. (Since I work for a children's hospital this seem most approprate).
You can contact the bike ride organizers and ask what teams may be "open" for "outsiders"!
I think this will help w/ the long distance logistics with camping and all. It is a PLUS if someone hauls my tent and sets one up for me!
Good luck w/ finding a team. Probably won't be hard!
