Eugene bars and restrooms

We're trying to figure out the proper etiquette and protocols for sex with strangers in public bathrooms in Eugene and Springfield. Eye contact? Foot tapping? Hand signals? And while we're at it, are the rules the same in Glenwood, Florence, Mapleton, Yachats, Coburg, Veneta, Elmira and Junction City? Local parks and rest stops?

Where are the best places to hook up? Any funny stories? Embarassing moments?
