Does anyone do this?

I have bad short term memory so before I got my ipod touch, I used to write on post-its and post then on the windshield. There's so much space! Ive been meaning to mention it here but kept forgetting.

 

Not a good idea.. police could issue you a ticket for obscuring your vision in most states.

 

Wel I put them real high, the same zone as the oil change stickers. I don't do it anymore of course, although the old ones are still there bleaching from sunlight.
