I have an upcoming nontraditional
Celtic Kilt Celebration taking place Saturday, April 10th to coincide with Tartan Day that is geared to attract a large contingent of kilt wearers as well as convince new kilt wearers (typically in the 100's). Not sure if it would be to your liking, though starting next year my plan is to expand this event to a week's worth of events and would enjoy your feedback.

FYI: We're going to make an attempt to set a Guinness World Record for the World's Largest Kilted Dance Party this year.
