<p>I will be in Boston next week for a school trip and will be in Boston again this summer for some college visits. I thought it would be cool to leave something- that is not very valuable, but not just a rock either- behind in Boston to see if it where I left it when I return 3.5 months later. What would be a cool object to leave behind and where should I leave it?</p>
<p>haha and you’re doing this why?..</p>
<p>what is prompting you to do this?</p>
<p>A letter…</p>
