Tagging bikes

Got a question+comment about tagging. When you do a track day at PI, the Superbike School puts a white rectangular sticker on your screen with the date on it so they know you're supposed to be there when you pull up in pit lane for your session. Every time they slap it on there I seethe. It's a bugger to get off and ruins the look of the bike in photos (IMHO).
When KSRC members tag bikes, do you stick it to areas that might potentially make the bikes owner mad? If someone stuck a KSRC sticker on my petrol tank/fairing/screen/frame etc. I'd be fuming. It wouldn't bother me at all if they put it on the seat (because it's easy to peel off and doesn't leave sticky residue), back of the mirror, tyre, heel guard etc. There's a lot of bike owners out there who are really pedantic about their bikes. Should we be more aware of this? What do you guys think? [/i]
