Taz gave some excellent advice.

The most important thing to remeber is not to get frustrated or discouraged. Patience is the key!

Also, if you have been hunting hard in one area and it isn't working out for you.....do some scouting to find where the deer are. In-season scouting is extremely important and some hunters forget that. Know what signs to look for.......if you don't know, then ask someone who does, whether on the net or in person.
