Well, it is now possible to register for Arcatheos! What is Arcatheos? It is the descendant of Camp Rivendell. It doesn't have a LotR theme though. It is closely affiliated with ConQuest a Catholic boy's program in this neck of the woods. Boy's from 7 to 12 years old can attend as campers. From 13 to 17 the attend as officers. (also known as councillors) Dad's can also attend, and for boy's 7 to 8 they are required.
The cost for the campers is $329 for the first boy in the family subsequent boys are $299. For the first officer in the family, it is slightly more expensive. It is $579 and $549 for additional officers. Dad's are much cheaper, they are only $229. Also, you can ask to join the team for $199 (you have to be approved before registering.)
