It took three days longer than we expected, but GallonDaily has just published its 500th article.

In recognition of this milestone we are offering our readers in Canada, the United State, and the United Kingdom the chance to win a package of 500 grams of fair trade organic chocolate.

All you have to do is to send an email to editor@gallonletter.ca with chocolate in the subject line and the answer to the following question in the body of the email:

Which is said to be Canada’s most threatened river in terms of environmental flows?

You will find the answer in a recent GallonDaily article. Correct spelling of the name of the river is required!

Also include your name, address (for mailing purposes), and telephone number so we can send you your prize if you are the lucky winner.

The fine print:

A draw will be made among all entries received by 9.00am Eastern Daylight Saving Time (EST) on Thursday 4th July 2013. The randomly selected entrant will receive 500 grams of fair trade organic chocolate by mail. Your contact information will be used only to send you the prize if you are the lucky winner and will not be used for any other purpose. Odds of winning depend on number of entries received. Contest limited to residents of Canada, USA, and UK. Persons associated with GallonDaily or Gallon Environment Letter are not eligible. The name and home town of the winner, but no other contact details, will be published in GallonDaily on Friday 5th July 2013. Decisions of GallonDaily and its publisher regarding the draw are final.

Good luck!
