What is the fine-grained topic of the following text: Mahalo to everyone who participated in Race Around the Island (RATI), including (but not limited to): padders from around the northwest, hula dancers and opening ceremony from Ke Kukui Foundation, chase boat captains and crews, race officials, raffle prize diners, spectators, park rangers (who understood that those bottles were full of root beer)… What a fantastic day! Only return the topic.
