As the season approaches, I have some questions for you all.

My friends and I have been debating the various laws of fireworks. I was wondering if any of you have good sites that can tell us what the laws are.

Someone I know found this link, but what I don't understand is this: the map on that site says that Pennsylvania is more restrictive than tight-assed Virginia where I live. This doesn't make sense to me, since I know people who drive from here to the Pennsylvania border to buy bottle rockets and such, which are prohibited in Virginia. So what is the deal??
