Actually my approach was based on order of sign up. Theoretically people could continue to add their names to the spreadsheet for the next several months. If many of them are from the South and the box continues to travel only to nearby states, those who signed up early but happen to live elsewhere would not get the box for a long time. So I just started at the top and began e-mailing people. Nate and Evan declined for now, and Nick didn't respond. Then I e-mailed Victor and Alan a day apart and only Victor has responded, so I sent it to him.
Communication on this has been tough. I had agreed with a guy in my city to meet up when the box came to him, and the box came and went without him ever contacting me. It's a great little idea though, and I like the spirit of it.
