I applaud your thinking outside the box. Around here we are finding that many churches are in similar situations. Combining resources is often the way to go. Because of this we are looking at forming a community wide youth ministry program around here. We had a full head of steam earlier last year but things cool off late last year. We are in the process of restarting discussions with the hope of being off and running by the fall.
I look forward to hearing more about your efforts and hopefully I will have more to write about mine. God bless.
