Step 1: Get in your truck, drive to wherever you plan on looking.

Step 2: Get out of truck and start walking.

Step 3: Look on the ground when you're walking.

Step 4: Look up occasionally so you don't walk into anything.

Step 5: You've found a shed! Woohoo!

Really though, all you need to do is get out there and walk around. They aren't going to be any place special, there really isn't any special place to look. You might try areas that are extra brushy, or where there are low hanging branches where the antlers are likely to snag and pull off.

Good luck!
