It's a ball, some of the most intense, nerve wracking, close up deer fun you can have with a bow!!!
You need a dried cornfield (with the leaves hanging down) that has grass in the rows (deer bed down on these grass patches, tend to avoid bedding on bare ground), and a windy day with the wind blowing down the length of the field.
Start about 20 yards from the downwind end of the field. Nock an arrow and stick your head into the first row, leading with your bow. Look right & left (or left & right if you prefer). No deer? Step into the row, stick your head into the next row, & repeat. Move across the field like this a step at a time. When you reach the other side, move about 20 yards upwind, and come back across the field the same way. Keep doing this back & forth down the field.
When you stick your head into a row and spot a bedded deer, the fun begins. You need to figure out which end is which and of if you're looking for a buck, if it's one you want to take a crack at. Compact binocs help.
A tip here, a bedded deer can make itself amazingly small and may not be obvious in even a small patch of grass, so examine & glass every patch carefully before moving to the next row.
You might have a shot right there, but most likely not. Ideally, now you back off a few rows and move down even with the deer, being careful not to give it the wind. Now you carefully move in for the shot. Often, you will have to quietly get to your knees and take the shot kneeling to clear cornstalks & leaves....
