I've seen this plenty of time when hunting near patches of thick pines.

The most memorable was when I was set up along the edge of these pines when 4 deer came belly crawling out of the pines. They were not on a trail, but must have been getting pushed by hunters on the top of the hill. They crawled out from under the branches about 1.5 foot of the ground. Stood up and walked away like nothin was goin on.

Pretty neat!
