This. This is a great picture of me. More impotantly is what's in the background. A freshwater stream in Yeongwol (province), South Korea. In which is an incredible amount of freshwater snails.
4 of us picked this in about 3 hours off of rocks in the aforementioned stream. Although we didn't soak them for 24 hours to get rid of any ingested sand and waste, they did taste and look great.
They have a nutty sweet taste that makes a great end to a long summer day in scenic Yeongwol province.
