That sounds like a great place.Man deer will pop out of nowhere in the swamp.It can be open enough to see for 150yds,then bam..there he is at 25 steps looking right at you,and you're wondering where the heck did he come from!!(True story).I have found that deer like to follow edges.Be it thick grass,against thin grass in clearings.Or in the swamps I hunt you have to look for an edge.Usually it will be a section of weeds or brush.Even though you can see through it any cover will be used.When the thin cover dies you will have to find something thick,or acorns.They will bedaround blown down trees too.I have even stumbled upon big upright trees with hollow cavities in the bottom,that had tracks in them.Now you think I'm crazy.There has to be a bedding area somewhere.I don't know too much more to add to what pass threw said.I agree with you.Most scrapes on roads and field edges are used at night.You still might catch one off gaurd at the first of the season though.Good Luck!!
