I've seen groups of 30-40 back in P.A. at nightime eating in soybean fields and such but never seen anything like that.  Wonder if it's real?

It could always have been 'photoshopped', but I can't see any clear evidence of that.  And, that would have to have been some work too!  The only thing I could think of why something like thiis would happen would be if that's a large cutover in the middle of the Canadian 'big woods' during the dead of winter, then deer might come from all around to get what food they could get from the undergrowth.

Tell you one thing! Might be worth the risk being a buck in that area! Talk about all the girlfirends you wanted!

Don't believe that I saw one antler in all of that. It was taken in a logging area. If you look, you can see stacks of cut tember.

Looks like a caribou migration.
