I wasn't going to post at all and I'm really not because others have done better than I could:
Random CR and Heathen ramblings... St. Patrick's Day, snakes, and Irish-American pride
Three Shouts on a Hilltop Leprechaun Vomit... or why I hate St. Patty's
Tairis The inevitable Paddy post
What ever you decide have a lovely day!
