I ordered a pack of 10 custom Riding In Riverside buttons from CafePress. I did this because I wanted around 5 of them, and it was cheaper to order 10 than 5. However, this leaves me with a surplus of buttons. They are 2" in diameter, with the Riding In Riverside logo on the front, and the blog's address below the logo.
And the next 5 people to e-mail me at email@example.com with their domestic mailing address and the word "Button" somewhere in the e-mail will get one.
Please, only ask for one if you'd actually consider wearing it about town.
EDIT: Addresses will not go on any sort of mailing list, nor will they be retained or used for any reason beyond sending out a button.
