Just a quick post to let you know, if interested, the National Wildlife Federation's 39th annual photo contest has started. It's open to all photographers worldwide who are at least 13 years of age. The contest ends on July 20, 2009. There are 3 divisions and 7 categories. Up to 20 photos can be entered for a $15 fee.
Here is the link for more information:
Be sure to read the rules carefully. I've heard that some contest will take ownership of your photos once you submit them. I don't believe this contest does that but it's something to be aware of.
