I agree with most comments. I would recommend separating compound and trad shooters either on separate courses, alternating weekends, or different days. Stakes should be color coded for Men, Women and children. Compound shoot black, and any of the lesser distances. Trad shooters Red, Green and White. If a man wants to shoot closer, fine. People that start on white should stay on white, etc. because the course is usually a challenge for most, as skill levels vary. A handicap system works for golf and might work here too.
I use to shoot the North American Longbow Safari. Their courses are usually tough, not all, but most. There were usually a couple different stakes. There were many lost arrows in groups I shot with, including my own. Too many targets were at long distances, over water, in water, trees, down steep hillsides, or up. Targets in brush and behind trees, generally took their toll on arrows. I remember a cougar on a rock wall, it looked like 90% the arrows shot there were still on the ground, broken. Another was a steel bear at about 35 - 40 yds with a hole the size of an apple. Unless you missed your arrow didn't survive. I thought people really enjoyed the running deer, and aerial targets as much or more than most of the course. I am sure most got the arrows back after they were picked up.
If you want to increase attendance, it has to fun for all and not a survival course.
