Socks and ramblings

I just downloaded the pattern for The Brethren Sock. I can't find a pattern for socks with larger needles and yarn, so I'm just jumping in. Now with the Brethren Sock, just a plain one. Also, do socks need to be blocked?
I am an addicted knitter, I take it everywhere. Dr's appts., long car rides, friends houses, even to picnics. I have no shame in what I do anymore.
