We’re very happy to announce that, through the generosity of Kailani Tours, we’re raffling off a Big Island Circle Tour for two (a $498 value!) to take place during the 20th HEAD meeting this coming March. The lucky winner and guest will experience the different districts and micro-climates of Hawai’i, with views of the Kona, Ka'u, and Hamakua coastlines, complete with wonderful stops in-between, sampling the island's finest coffees and sweet treats before heading to a black sand beach and Hawai‘i Volcanoes National Park, and finally visiting the scenic Rainbow Falls in Hilo before cruising back along the beautiful, lush Hamakua coast.

The raffle will be held during the HEAD Social and Business Meeting on Tuesday, January 10, 2023 from 7:00 PM PT - 8:30 PM PT at the 241st AAS meeting.

Participants in the raffle are intended to be HEAD members attending the 20th HEAD meeting, so if you’re attending the 20th Divisional meeting of the HEAD, come take your chance for this tour of the wonders of Hawai’i.
