Sunrise, Sunset -- the sky's the limit

Send a picture you've taken of a sunrise or sunset, include a note about the location and circumstances.

Not a lot of rules -- you pick the size you want to send, send it in an envelope or send it naked (but try to protect it as best you can with cardboard or lamination), and send more than one picture to your partner if you'd like to

(In order to be mail-able, size needs to be at least 3" by 5" if mailing naked}
