MOABS.. Anyone heard of it/been to one?

It's an event called, The Mother of All Baby Showers.....So I received my Buy Buy Baby registry bag in the mail today (they mailed me 1 since I don't live near a store, got some cute stuff for free). Anyway.. included in the bag was a coupon for a ticket to The Mother of All Baby Showers. I did some research & decided to get the VIP ticket which after the coupon was only $48. With the VIP you get a free K'Tan diaper bag (I looked them up, $60 - that alone pays for the ticket) & swag bags (bags filled with samples & products). Has anyone gone to &/or heard of one before?
