This is the final week of the contest before Simm's announces the grand prize winner, so it's your last chance to snag a pair of Simms Pursuit GORE-TEX shoes. Of course, we've saved the most challenging mission for last. This week's topic is underwater. Now there are lots of relatively inexpensive underwater cameras out there these days, so let's see some cool fish release shots, fight shots, flies underwater...anything goes. Shots taken from above the surface that capture something below count, too. Email your underwater photos to email@example.com and check back next Tuesday (Monday is a holiday) to see if you won in the final week of competition. All underwater photos must be received by midnight on May 30th. If you missed them, click here for full contest details.
