It should be noted that a lot of the images placed on side 1 of the field do have meaning. There is an image of lightning, BK was struck by lightning (I don't know what year) and it sent several members to the hospital. If you watch the show two members end up standing in front of that image with hands over their hearts, then then move to the back and seem to strike poses of fear. Now there is a chance I read too much into that. It could simply be a reference to a line in the corps song 'I Go On'. The line being "When the thunder rumbles". Now that I think of it the entire show seems to be reminiscent of 'I Go On".
