Two words - company car... Not crazy in itself, but my coworker came in with it and asked if it was my "weird pen-thing".
Here I go quoting myself again:
Reading your story made me wonder what happens when a person who has never heard of or seen an e-cig (e.g. another hiker taking that same trail a day later) happens upon one. What goes through their minds? What do they think it is?
You answered it! A weird pen-thing. Damn, I was kind of hoping for something more interesting. That's people for ya.
