Okay, I would like to do the pie ride and have read the "traditions" regarding it, however, the guidelines are rather vague. I don't want to be DISQUALIPIED for not following rules. Must I be part of a group or can I do my own ride with just a witness? Will you take me at my word or is the "if there are no pix it doesn't exist" rule in effect? If so, does my bike and the pie have to be in photo together?
