If you do not have the opportunity to pre-scout your hunting area ahead of opening day--you can still do some work with aerial photographs(topographical representations) to obtain a overview of your hunting location.This may afford you an quick reference to bodies of water/swamps--potential animal travel corridors--other features that are inherent to your location.If it is opening day try and determine what adjacent hunting pressure that may exist within your area and how this might impact your own location.I always equate opening day with the boxing day sale at your local Wal-mart---just a whole lot of activity-four wheelers-pick up trucks and everybody out for a walk in the forest looking for the big deal.
