Well, as you can see, it is a public outreach poster for a planning process that is designed to grab a passerby's attention. And it works, at least it did for me. It asks you to think about what you'd like to see for the future of Boston and directs you to a website to give input: futureboston.com.
The website is designed with four simple questions that, together, tease out your vision for Boston's future. I encourage you to give your input - I did.
