Bumper stickers are a personal choice that all vehicle owners have to make for themselves. I don't personally care for them and it's not because I'm worried they will wreck the look of my Saturn.
I don't like them for reasons like this: I was driving behind somebody today with 2 stickers on their car. The first one was something about freedom or war is bad, something like that. And then the second sticker, was one of those I heart Ferndale in this case.
Interesting that this person will defend the country on the back of the car, and then on the same bumper, they've put a sticker I love my hometown. And these were given equal placement on her car.
Who know you love it. You live there, I just don't understand why you feel the need to scream that on your bumper.
