So i have been hunting this state land out in Long Island.  I have not had much luck as I do not know the area that well.  i did some scouting and here is the scenario, any advice or tips would be appreciated.  Basically the land has a giant bog/swamp on it.  The swamp is probably about 7 or 8 acres big.  The swamp buts up against a road which is where I park.  I walk around the swamp and then behind the swamp is about 10 acres of some thin hardwoods of oak trees and Pine trees but the ground has very thick tangled brush everywhere.  I dont know what you call that stuff but its about 3 feet high and extremely tough to walk through. There are trails that run through that thick stuff down to the swamp.  I had been set up on the edge of the swamp where i found a few shredded pine saplings and a couple of old scrapes but i did not see much.  Now behind that 10 acres of woods and thickets is a huge open grassy field.  I would say its about 3 football fields big.  It looks like long whitish dry grass that has been bent over and pushed down.  i have not hunted that field yet.  So heres my question.  I always see deer come out into fileds, golf courses, open areas at sunset.   I assume they are feeding in those fields.  thiose fields usually look liek they are greener.  How would i know if they are feeding in this dry grassy field.  Do they eat dried grass??  Where would you set up if you were me?  Thanks
