After the opening ceremony all of the conference participants walked to the castle for the opening reception. The guy behind me joked, "The nerds are storming the castle!!" When we arrived the military was practicing their musical marching for their upcoming military celebration. We walked in and their were lines of bagpipers and drummers, all dressed in different military uniforms. It was amazing! Some were in traditional highland tartan kilts, some were in modern blue uniforms, some were in camoflauge and some were in hybrid uniforms that had the modern blue top with a blue kilt.
