I was raking the leaves around my chicken pen today and encountered the most enourmous spider I have ever seen other than a tarantula (I had to look that up to spell it correctly). Anyway.... it was very aggressive. I managed to get it into a glass jar and looked it up on the web. It is a female mouse spider. I don't know how to do links to a picture and it is too scary and dangerous for us to try to photograp it ourselves, but you should really google this thing and look at it. We discovered that it is very poisonous and can inflict a nasty bite. One site said it could be deadly to a small child. They don't build webs, but instead dig holes in the ground. I'm worried because usually where you find one, there are others. I hate spiders!
