My hopper and I just got back from a 3D matinee of Dr. Strange. Nothin' goes better with some kickass vaping than some mastery of the mystic arts. I'm hoping the theater staff finds my eyeballs and mails them to me soon. Lots of fun!! Especially since I was the only one in the theater - my idea of heaven. As the previews start I pull out my hopper with a MFLB stem in the silicon condom. Click it on and 5 seconds later I'm "putting on my 3D glasses" before I even open the plastic wrap on the ones they gave me on the way in; clicking merrily on and off as I take my hits. As I'm pulling my third (or was it fourth?) hit, an usher comes in to do that "security walk" up and down each aisle. Didn't expect him quite that early. Don't know what he saw as he walked in behind me, but when I noticed him at the end of my aisle I just slipped my hand loosely around the lights, clicked it off and dropped my hand to my lap. If he saw anything, it obviously didn't bother him. Once he left I resumed. Finished off another couple of hits, tucked the hopper back into my pocket, and enjoyed the show. So yeah, those little lights are pretty bright in a dark theater. For propriety's sake I'll be working a bit more on my stealth mode for those kinds of situations. I had brought my Smoke Buddy filter with me but wasn't using it since I was alone. Again, if he smelled anything, he didn't react.
