Arson: Potential Hobby?

I want to destroy billboards; I've decided that advertising is the most horrible industry ever created. So there goes another job option. I'll never be an ad-man, unless I sell out at 25.

The best way to destroy them, I think, would involve The Deathtrap and a quiver of flaming arrows. As Al pointed out, there just aren't enough intelligent arsonists out there.
