Rock shopper back blip

I went to my folks house today to get them a few more things they needed to be comfortable at my sisters while my mother recuperates. So, I thought I'd pick up a few rocks along the shore for her to paint. Another project to keep her busy since she never sits still. She is pretty good at painting and took classes for years.
Anyway, I was pleased to find the rocks along the shore covered in nice size oysters. The creek must be pretty clean to have such a large crop. It helps to have a large oyster business down the creek from her who's oysters put out spat year round.  
Then I felt bad taking the rocks so I got a few high and dry where oysters would not live anyway.
