Wow, I have had a whole new insight into Echo's world of phtoography, thanks for sharing!By the way my dear friend Aaron is also a reporter and photographer here in our little town. He is on my friends list on Facebook and he has some amazing photographs on his page, check it out if you get a chance (his last name is Morgan) and he had a great quote I thought you might like: Sometimes I do get to places just when God's ready to have somebody click the shutter.
