Today, I went to the beach with my kids. I found a sea shell and gave it to my 4 year old daughter and said "You can hear the ocean if you put this to your ear." She put the shell to her ear and screamed. There was a hermit crab inside and it pinched her ear. She never wants to go back! LoL I know this is totally off topic but I had to tell someone! Good post however I was wanting to know if you could write a litte more on this subject? I'd be very grateful if you could elaborate a little bit more. Bless you! Wyoming Valley Equipment LLC
