I created my own. At my house in which I now let my sister stay I have a 5 acre wooded lot and a large basement. I use to have the young people over from our church where I would organize the following activity...
1. Late Afternoon - Grill out and play outside games
2. Early Evening - Open the basement up for fun and fellowship
3. Evening - Have a camp fire and special speaker
4. Late Evening - I would let the young people hang out as long as they wished.
I used to get anyone I could to speak, and if they could not put together a message a testimony would do.
