Well, from May to September you can go to the town square at 8:00 and watch the Pipe and Drum band march up and down the square and play a few tunes. Here's a short video to give you a taste of Scottish culture. Sorry it's kinda dark, but you get the idea.
After that some cute little girls do some highland dancing on a stage in the square. I was going to get a video of them to share with you, but it was kinda chilly and we got tired of waiting, so here's a clip of some random highland dancing. The show we get in Dornoch is similar to this, but with fewer girls.
