Dear Cirque attendees, past & future:
More than likely the answer to the subject line question is "I didn't know that there was one!"
(And that's because I dorked out during the running of this year's and forgot to bring them to the various events this year!)
And so it happens that I have a small batch left (some insiders knew about them) and have just taken a photo illustrating the shirts. Fetchingly worn by CDO staff members, see them here:
These are top quality 100% cotton silk-screened tees. Limited sizes are available, see the web page for info and ordering. Please no e-mails as I am off to Interbike; instead talk with the friendly CDO staff.
