It started with a Facebook invite, "Queer Kissing Flashmob," sent out by some HSU students:
"Come meet us on the HSU quad to kiss your partner(s) at noon on Valentine's Day! Please wait until the clock starts to strike noon to start kissing your partner(s), kiss for between 5 to 10 minutes and then go about your day as you normally would."
Marriage Equality USA (requestmarriage.com) found out about it, suggested putting it in their national newsletter. With that Queer Flashmob spread to Eureka. "We're encouraging people to make out in public wherever they are on Valentine's Day to raise awareness for diverse sexualities!"
