I didn't read all the responses so; I may be redundant here but, this is what I would do:
1- I would pull down as much of the flagging as I could manage.
2 - I would find another place to hunt. The presence of all that flagging says that the place is too popular and you'll be tripping over people throughout the season. That's as close to a guarantee of low-to-no success possibilities as I can imagine. The place may look good now but, no animal is going to tolerate flocks of hunters in the area.
On public land you've got to find just one thing - reasonably productive area where others do not, can not, or will not go. This usually means going a lot further (or sometimes, a lot closer) than anyone else into mean, mean territory.
