I was out I was out getting silverfish for my blue belly lizards. And underneath one of the two by fours on the deck was this pretty large spider. which I have never seen in my 50 years living here. I like spiders because they eat mosquitoes and other nasy pests. so can you help me identify it?

Dear Fixitwill,
Though your image lack critical clarity, we believe this might be a female Crevice Weaver Spider in the genus Kuculcania.  See BugGuide for some images.

Wow thank you so much for your time!! It was hard to get a good picture because it kept moving around on me.
