Actually I think this is a 'Herring Gull', Laughing Gulls have black heads according to what I could find on the internet. There are black headed Laughing Gulls at the Wal*Mart but the one yelling at us today in the rain had a white head.
It started thundering and raining around 3am and has stormed and rained all day long. I think our 4th picnic will have to be cancelled, it is supposed to rain all week. I do believe this is the wettest month of June here in Charleston, since I've been living here (16 years).
