Wow! Thanks for all of the great info and the ID!
I also have a daughter, 9 years old, who loves to go MDing with me. She was the one who talked mom into getting me the MD as a Christmas present. She was not with me on this short trip as it required a hike down a very steep muddy bank. About 300 feet verticle with large rocks, broken glass, and assorted stuff that people have decided to dump over the side. The area is a like a history of American beverage transport... apparently drinking cans of beer at this part of the creek/river is a tradition that is passed down from generation to generation.
That was the only really neat thing that i found in a few hours of hunting. But being outside on a spring day, hearing the water as it bubbled along, the ducks quacking at each other... that was the real treasure on that day.
Happy Hunting!
