Although not a member of the SxS Society, I've attended a couple of their shoots as a guest. They are well run and always feature a terrific lunch. SoCal is hosted by Jim and Jerry of Ivory Beads,

Nice guys, great guns.

Often times feature displays of members beautiful doubles. I thought I'd interject a little levity at one display and called out asking if those guns were the 'rentals". Received tons of laughter and 1 menacing glare.
