Mailbox Challenge

I would like get away for a second from the computer based society we all live in and get back to what's important. Postcards. This year's Mailbox Challenge 2006 will be very simple.
Rules:
Get a novelty postcard.
Write "Wish you were here!", a short message and sign with your nickname only.
Get a sticker roughly 3/4" x 3/4".
Affix the sticker to the postcard.
Address postcard to my friend;

Carl Nostrander
4727 SE Franklin
Portland OR 97206

Mail them from a streetside mailbox.
NOT from your office or home.
Carl is just interested in whether or not the mail will be delivered without adequate postage and without a return address. It is in the interest of science that we attempt this.

Best postcard received by April 1 will receive a jar of whole peppercorns from Penzey spices.
