A lunch hour run to Bill Miller's is boring. Satisfy your midday meat craving another way. Those cars in the parking lots of, say, the Ranch Motel off Broadway, or the Fox Motel next to Pearl — the drivers aren't there for the five-star amenities. It's reasonable to assume that, behind many of those locked doors and drawn black-out curtains, couples are having dirty, dirty day sex. Scratch another notch on your San Anto bed post. Grab a friend with benefits — maybe two? — and rent a room for some nasty nooner naked time. And, no, we're not talking about tender, intimate lovemaking. We're talking noisy animal sex. Ranch Motel, 3101 Broadway, (210) 826-2304; Fox Motel, 302 Newell, (210) 225-2418
