You are 100% correct on your last statement. You can't kill one if your not hunting them.
And to try to use camera photos as the time to hunt is probably not the best strategy. But, any info I can get may help in some way. I'm curious to see how the numbers from this year line up with what I compiled yesterday.
Another fly in the ointment is where cameras are placed at certain times of the season. Some are placed at funnels, some over scrapes, some here, there and anywhere.
When you eat, drink and sleep deer hunting, you have to spend the off season doing somthing.
