You can find a lot more information by going to these links attypops. These'll give you a better idea what the gala day is all about:
Loanhead Gala Day - Midlothian's oldest and largest local festival
This site gives the best reflections of decorated houses
Lanark Lanimers
This is arguably the biggest and best gala day. It even has it's own name "lanimers"(nobody knows where this name comes from)
and finally our gala day. Carstairs is a small village about 3 miles from Lanark but has it's own smaller celebrations. It doesn't have it's own website but you can see some of the photo's from previous galas on here.
Carstairs
Good luck Becks with you GI tests (whatever they are?*wincing at the thought*) I'll assume they are medical tests as you feel the need to fast. Hopefully you'll score top marks, (or low marks if the test dictates that high marks are a fail)
Good luck from me anyhow.
