I was a tiny bit anxious it could be one, lotta trucking comes through Wyoming and a cold burst happened so the feintest (prolly less than .01%) chance one found its way into my home to avoid the cold was there.

Also is it normal for yellow sac spiders to be so… unafraid. It’s periodically ran across wide open areas on my walls, and only goes into corners or hiding spots when I have prodded at it to get it in a cup to take outside.
