Question
I was looking at a tree in my backyard and a huge, I mean huge spider was peeking out of a hole and he went back inside.  He really looked like a tarantula size that I have only seen in a pet shop however he was brown, hairy and had orange on him.  It was a poplar tree and I live in Virginia...What could it be?

Answer
Sounds like a wolf spider.
Female wolf spiders are large, hairy, running spiders, often confused with tarantulas. They may be brown, black, gray, white, yellow, orange or green. Many have a stripe or pattern the length of the first, and sometimes the second, body segment. They are nocturnal and usually occur outdoors but may wander indoors, especially into cellars and basements in late summer and fall when cooler temperatures prevail. These hunting spiders, which do not construct webs, carry the large, globular egg sac attached to spinnerets under the abdomen. Upon hatching, the spiderlings climb onto their mother's back and ride there for several days before dispersing. They do not establish themselves indoors and are not aggressive, but may bite if handled or molested.

Here is a web link to a spider ID chart that might help.
