That's why my sign is close to the front window. It would take quite a off-road adventure to get that sign.
Not that I'm real worried about that in Georgia where Bush is going to win by double-digits.
Don't be too sure. I lived down the street from one house in which a pickup drove through the living room window and was lodged there for hours. The house is still trashed and it's been over a year. (no political signs involved)
