Leave sandcastles on the pavements with little flags promoting your summer sale. Or beam your logo into the clouds at night. Just be careful not to go too far. Do something to attract attention both from the public and the media. It should be related to your business in some way.
Thanks for sharing.
This reminds me of Richard Branson’s methods of catching attention and marketing at the early stages of the Virgin group. Imagine flying a balloon over the city just to create attention. Crazy stuffs, but it works.
