St Paddy's Day or Alison Weir

March 10. I can either go to the Saint Paddy's Day bloodbath which I & Miss Ginsie would love to go to or I can go and see Alison Weir give a day long presentation of the Tudor Era Queens and maybe get her latest book about Jane Grey signed. I have no idea which one to go to. I've never been to a local SCA event that was over $20 so I know St. Paddy's Day won't be much $$ and the Presentation will be $85 for Smithsonian members but it's a presentation by Alison Weir! Argh!!
