For more reasons then just the fact that it's spring. Have a look at this. And I've had folks telling me I'm paranoid. Yep, keep sayin' that.
I'll just continue to stock up on my gardening supplies and such. Because, like the expression says:
Just because you're paranoid, doesn't mean that they're not out to get you.
Hope for the best, plan for the worst, and such... :p
