Funny you should post this rant...I've been ranting about this to DH for months and have been meaning to write it up as a rant here but never got around to it.
Here in TX, those damn stickers are all over the place! And invariably they're on the back window of an SUV or Minivan - I've only ever seen ONE such sticker on an actual normal-sized car. Breeders and Hugh Jass Vehicles - they go together.
And yeah, 9 times out of 10, the boy's sticker is for a sport and the girl's sticker says "Cheer" or "dance" on it. God forbid the girls should play an actual SPORT! (Not that there's anything wrong with dance, but geez!)
