Sad but true, I did scribe my website name into the very thick dust of my boyfriends back window on his van. Instead of putting "wash me please" I traced through the dust and gave him a big fat dot com in his window, lol.

But a more sensible approach would be to offer some sort of freebie and have people sign up for it. You could generate a nice mailing list this way without really tricking anyone. There are still a few good seed webmasters out here and we need to let folks know this.

Print some business cards, flyers, or postcards, and place them on hotel desks or their brochure rack to get yourself somewhat exposed.
