I was talking to my daughter last night and she mentioned that she was getting cold smoking outside again (she has 3 kids and won't smoke in her home) and said she was smoking a lot more the last couple of weeks. She's starting a new business and I know that's a strain. I just ordered her a 510 starter kit and enough liquid for a couple of weeks and I'll show her some of the ins and outs when it gets here. I couodn't think of a better present for her.
