Did you go on a stand and wait or did you slowly walk around? If you kept moving, you probably moved deer to the other hunters. The trick to hunting with large numbers of hunters around is to stay put and let them move the deer to you. Scout the area well ahead of time to find some well-used trails and then pick a few different spots to stake out. And try to stick it out from first light to past noon - often, at about 10AM or 11AM, hunters will move around or go back for lunch, moving lots of deer.
When I was growing up, we did deer drives with lots of hunters (very unsafe), but they were always on private land. You might want to look into "two man deer drives" or "three man deer drives" but I think on public land you would end up moving deer to the other hunters.
