I love searching for Sea glass with my 11 year old son...

My son has an amazing eye for finding sea glass... he can spot a piece that I just walked by. I love to walk up and down the beach with him and for every 1 I find he'll find at least 10...he jumped in the marina while we were at the Lake Erie Islands and filled his pockets with glass...he was bending over picking up glass as dead fish were washing up at his ankles and he still didn't quit! I hope we'll find some good sized red, yellow or orange shards soon...he did find a little red tiny. So far the Great Lakes have been good but we need to get to the ocean! Maybe next spring in Florida?....
