Rear Window Decal

[PerfectSum]

Hello everyone,

I unfortunately need a decal on my car to park at school. The only two options are on the rear window of your car or on the rear bumper. I would like to avoid putting the decal on the rear bumper, but I feel like the decal would be very hard to get off of the rear window. Does anyone have any experience with this, or know if a sticker on the rear window is a bad idea? Thank you very much!
