Tom Vanderbilt — author of a book everyone should read — wrote about the diverging diamond intersection in his column for Slate. The first one in the U.S. was built right here in Springfield. I’ll be taking my CyclingSavvy class through that intersection tomorrow

How many students do you have? Good luck, Andy.

Posted 30 Sep 2011 at 12:42 pm ¶Robert… 5 students. And thanks! It should be fun.
Michael… It looks imposing, but is actually quite easy to negotiate.
Posted 30 Sep 2011 at 1:51 pm ¶Have a great class this weekend! I can’t wait to hear all about it!
Posted 30 Sep 2011 at 3:54 pm ¶Who (in general) are your five students? Do you know any of them?
Posted 30 Sep 2011 at 4:14 pm ¶Are you doing this teaching solo or who is your partner in crime?
Posted 30 Sep 2011 at 5:10 pm ¶Robert… My wife and daughter were two of them. As you know, filling classes isn’t easy. But they needed it no matter who was teaching it.
Steve… CS is normally taught in pairs. My partner was Karen Karabell from St. Louis.
Keri… Will be posting soon.

Even now, I’d guess that most of our students are people who we have some kind of connection with.
Posted 04 Oct 2011 at 11:22 am ¶Robert… I knew one of the others — just not a part of my family
The other two were unknown to me. Both came in from Facebook.

Posted 04 Oct 2011 at 3:35 pm ¶Andy,
Glad you had some takers. Good job.
