I say it's a good idear. But to cut it off by Sept would proablly mean not catching a lot of pics simply because that time frame does not cover the rut. You will miss all the scrape making, buck fighting, and even matting pics not to mention the bucks that move into entiely new areas during this period. As a start up time I would include May as you will get some new born fawns at that time. Catagorys should proablly include Whitetail, big game (bears and such) small game and a most unusual catagory just to name a few. To keep everyone honest a date and time imprint should be on the pic to be valid for entery to keep past pics from being entered. Just a few thoughts.
