Last year was March 1st in my area, this year they were still packing on March 15th and half of them still packing on the 21st. I think over the past few years I have figured out that they fall when they fall and not a minute before. I have pics on my game cams of them fighting last week, antlers locked just waiting to see them drop in the next frame.... but nothing.
Maybe this weekend I will find the matches to the three I found last week.
I think I have seen the match to one from last year in another thread. The pic of the antler looks just like the game camera pic of the guy I have packing it on private property. Gotta love your neighbors, I guess no trespassing only applies if you are there to enforce it.

Good luck out there, with the light snow this year they are going to be spread out, you are going to have to burn some leather.
