I used to pass flyers for car shows and swap meets wherever I went. If someone was attending a car, I handed them a flyer. If no one was there I dropped a flyer on the seat if a window was open. I never stuck one on a windshield. As for myself, I lived for flyers for future events. In fact, I kept a large stack from previous years. If I had nothing scheduled for a weekend, I would go through my stack of old flyers and make a few phone calls until I found something going on.

Of course, that was all before information became so easy to find on the internet.
