I totally get that frustration. I had the exact same issue with my organic juice bar last summer. Digital is great, but it’s so saturated. We actually decided to experiment with Mobile Billboard Advertising and it was a total game changer for our weekend sales. We used a service from http://therollingads.com/ and what I loved was that the truck could literally follow the crowds. When there was a local food festival or a big game, our brand was right there circling the block. It’s hard to ignore a massive moving screen compared to a tiny 5-inch display! My advice is to keep the design super bold and simple. People only have a few seconds to look, so don’t overcomplicate it. We saw a huge spike in "new faces" who told us they saw the truck while waiting for the bus or walking their dogs. It’s definitely worth looking into if you want to dominate a specific neighborhood.
