curious to your guys opinions on opening day tactics and game plans..

im hunting a spot that is absouletly amazing to me right now opening day. its got IT ALL. white oaks dropping...2 crab apple thickets, grapes, corn field 100yds way, hedrgow between me and the cornfield, thicket behind me, and the hardwoods is pretty thick..and surrounded by a stand of pines..my spot is the only opening and 4 trails come together there. im in a stand of like 5 hickory trees. i dont know how itll pan out in the morning. i dont know where they will be or what..its all too hard to call. they could be bedded in the hedgrow infront of my stand..could be in the thicket behind my stand...could be farther away. im hoping they head there for a morning snake. but i think that will be a hotspot come evening..hard staging area before they go into the fields i think. just curious....what would you guys do? also keep in mind other hunters will be all around all the other woods..doubt anyone is near me...from the road it looks like a stand of pines..but i dont want them to see me leaving there. im considering an ALL DAY stand. DARK TO DARK. taking a big sub, water, jerky etc to hold me over. it dont get light till about 630ish at the EARLIEST so ill leave here 5am LATEST..10 minute drive away. is sitting therea waste of time or worth while?? ive never made an all day sit before...im bringing a book too..i have a feeling it may be SLOW mid day...but i dont know.....dad says im crazy if i get down...exspecially with other guys all around me...never know when they are going to get bumped right into my setup.....what would you guys do?
