BPS, the link is to a camera, not a feeder.
On the feeder issue, our club has feeders on almost every foodplot. They are a big factor as far as seeing a lot of deer activity and enjoying a hunt. But the presence of feeders really doesn't have an effect on our herd. Club rules limit each member's kill to a level below State limits and we've proven more than once that our overall take is the same with or without feeders. For example, because of the high price of corn last year about half of our members didn't run their feeders, but they're kill was right in line with the members who did. We spend a lot more time watching deer than shooting them.
