Last year I dropped in at the SFO mid-dayish on the Friday before the seconds sale. About a dozen to two dozen people were lined up on the walk in front of the store off to one side so SFO daily activity could still happen thru the entry unobstructed. There isn't much of a lobby and they weren't allowed into the lobby to wait it out. November in Colorado is usually cold, so some tough hardcore souls braving it out thru the day and thru that night, but looked like they were having a good/social time (drug and alcohol free of course). Some got a little restless when I went in and came back out with a package in my hand (picked up a mule and yes had to pay regular price as it was a regular business day and was business as usual, just a crowd starting to amass outside). The regulars had to explain to the newbs that SFO was open for business as usual and they quickly settled back down. If I recall correctly, a bunch of porta potties were on hand in the parking lot for the event/crowd.
So many knives - so little funds!!!
