Even in this era of global warming, there are large areas of the inhabited world still covered in snow. Some of these regions are populated by people with money to spend and therefore a pressing need to be advertised to (eg ski resorts).
Today’s invention is a set of snow chains which, when fitted to a giant 4×4, will allow it to leave behind wide tracks advertising some product or other. The links in these chains might even be reconfigurable to allow users to advertise their own local restaurant url or other apres-ski entertainment. They might just say “…Party –> Party –> Party –>…”.
My postman wears snowchains on his boots in winter and so individual shoechains might be similarly constructed, with an advertising function in mind.
