How do you smoke when it's cloudy out? Or do you take the day off?

I will say that I haven't really "vaped" with the sun... just used it, in conjunction with a magnifying glass, to ignite a bowl and keep it toking. I see what you are suggesting and next time I get some sun around here... I'll give it a shot. :hippy:
