I wasn't sure where to put this here or "caving in the News", but since it's in a youth group specific magazine...
There's an good article in Scouting Magazine on a Boy Scout Troop's caving trip and how it was planned and carried out. Scouting Magazine is a BSA periodical for BSA Adult Leaders.
There was even a plug to look for help from the NSS at http://www.caves.org.

Check it out. Feel free to give your feedback.
