Photography Fundraiser: A giveaway

Hello all!
The response to the fundraiser has been great, and I want to thank all of you who have ordered prints. The latest batch is in, and after Labor Day, I’ll get those mailed out to you.
Speaking of the new batch, I also ordered an 8×10 print of this:
Kawishiwi Falls, Iron Range, Minnesota
This is Kawishiwi Falls on the Iron Range in Minnesota, and as a thanks to those who have ordered prints and made donations, I would like to give this away to someone in the U.S. (Sorry, International friends, the shipping outside the U.S. is a killer).
So, if you would like to be in the giveaway, send me an email: jvstin [at] gmail.com. Use the subject line: Kawishiwi Giveaway, and answer this question:
What is your favorite waterfall.
Please include a valid address so I can send the winner their prize!
Contest ends Midnight, Central Time, September 7th. One entry per person.
