Me and my buddy swear by bullets for venues and walks.

Hands down best stealth device I've ever used; would never go back to a bat/dugout after using this. It's a small vaporizer -- no flame, minimal odor (nothing compared to smoke) that dissipates in seconds. If used outdoors, can't tell unless I blew vapor in your face. Side benefit of being extremely efficient -- more so than a one hitter.
