Ahhh...I see your point. My dad told me to avoid planting during the passing of Halley's Comet. Something about the spirit of the plants being sucked-up by the stardust that follows.
To each their own.
I'm also not a believer in lucky talismans, horoscopes, biorhythms, divining rods or pyramid power. If you feel more comfortable believing in folklore, fine. Just make sure the tales you believe in, do no harm.

I have never once seen anyone actually do a blind study of this, and thusly remain skeptical. Till it's proven, it's all conjecture. (proving your stance thru pictorial expression is of course acceptable...)
