I had the same thing happen to me a couple weeks ago on opening morning of Turkey Season... Was walking into a clearing and out pop 5 deer. I freeze. 4 keep feeding, but one stomps a bit and moves towards me... This went on for about 10 - 15 minutes before I decided I had had enough of the game. I got up and kept walking, they took off.

Guess what? it wasn't ASAT, it was Real Tree Hardwoods HD. Yeah, you heard me.
