ABSOLUTELY NOT. Taking shelter under the most likely thing to be struck is exactly what you are not supposed to do. The "educational video" way to do it is to crouch down in an open area, proffering your buttocks to they sky gods, presumably making them self conscious and less likely to go through with it.

Also, carbon conducts electricity too, and if a tree or a telephone pole is adequate ground for a bolt of lightning I wouldn't put much faith in a bamboo frame either.

I never used to be afraid of lightning, until I was making my way home after sunset one night in August with frequent flashes to the East when the brother of someone I went to high school with was struck and killed outside his house the previous day. It made for a surreal commute.
