Polonius3:
Do Scots have any special St Andrew's Day festivities or are these simply general, occasion-non-specific celebrations?
In Poland the fortune-telling theme predominates.
Yes, szkotja2007 posted a link to some of them in his post.
Anyone driving over or who is near the Forth Road Bridge this weekend will see the two giant saltires raised on the bridge. Similarly they might see the saltire projected onto the clock faces at the Balmoral hotelin Edinburgh (proving so popular it might be left until after New Year).
Currently, Burns Night is more widely celebrated than St Andrews Day but it's becoming more popular, it's more "officially" recognised now, especially with the introduction (as szkotja2007 mentioned) of the bank holiday a couple of years ago. I think that people at home will celebrate it with a traditional meal of haggis, neeps and tatties. Bigger celebrations will include ceilidh-dancing plus haggis meal.
