Next Vinyl Record Sale - July 6th

I'll be having another vinyl record sale saturday July 6th - indoors in the air conditioning - at my office at 1739 St. Mary's Ave. I hope to blend that into a late afternoon film showing of the Steve Goodman movie, if I can arrange to make it dark enough to see the movie in the daylight; I'm looking for a creative solution. I'll try to figure a food theme, too, to make it a little potluck type thing.
