Who Should Streetsblog Interview Next?

As longtime readers have doubtless noticed, when I travel I try to fill the space on Streetsblog with guest posts or interviews.  To that end, I'm hoping that all of you have some suggestions of interesting people to interview.  I can conduct the interview online, such as the interview posted last week with C.I.C.L.E.'s Liz Elliott or in person such as the interview with author Erik Knutzen.

I'm hoping the interview series will talk to some people who are doing interesting work around the city on Livable Streets issues.  I got some interesting ideas from the this site's Livable Streets Network group, which is open to anyone, and hope to hear some good ideas in either the comments section or by emailing me at damien@streetsblog.org  soon.
