There really isn't any exact science that can be applied to the art of shed hunting since they can drop at any point and some drop a month before or after others however I have found the best places to search are winter meeting areas, places main trails cross creeks, fences, any place a buck might have to jump or duck under an obsticle that might jar a loose antler is a good spot. You might also try entry and exit points of feeding fields. Some years they just pop right up others you might not find a thing. I would say that since you found 2 last year that's not to shabby
