If you are in a cold-weather city where it snows a lot, Shoveling Elvises is a great stunt that could turn into a winter-long promotion. It can also create a lot of attention. And, you can extend it to other seasons with a little creativity.
There’s not a lot of work involved, especially if you have a promotion team or interns that can be your team of shovelers. If not, you could hire out the shovelers.
