We’re so gosh damn lucky, we big gays, aren’t we just? Magical creatures that can do fabulous things others are simply too silly and/or hidebound to achieve. Things like being in your 20s for 40 years, for example. And not accidentally getting pregnant ever (that’s a biggie for me—you, too, I’m sure). And chief among them all is the ability—well, it’s more of a biological imperative, really—to roller-boogie to the irrepressible soundtrack of The Rocky Horror Picture Show. Firstly, it hearkens back to those glorious days of gay yore when gay skates were quite the thing (RIP, Gay Skate in Bellevue, I loved you well). Secondly, science fiction! Double feature! There’s a light! At the Frankenstein place! TIME WARP AGAIN! In skates, though! You know you want to. Just try not to kill yourself. Southgate Roller Rink, 9 pm, $7 (includes skate rental), all ages.
