If anyone is off on Friday the 11th and would be willing to be my boothie, the Celtic Festival is a smallish Irish/Scots deal in Buffalo on a Friday and Saturday (DH is planning to be there after work Friday and all Saturday with me).
After setup there should be plenty of time for running around doing kilt checks and learning Gaelic (there's usually a booth giving free lessons!) and they have Haggis at the food tent. You do NOT have to wear garb, though if you want to it's fine.
