What is the meaning of "airing" in the context below? Hello everyone! Could you please help me with the word "airing"? "These camps offer participants the opportunity to experience several different outdoor adventures during their summer weeklong programs. Activities may include: rock climbing at one of Alabama’s own secluded climbing areas; airing in the Appalachian Mountains of Georgia, Tennessee, or North Carolina; exploring the underground world of caves in Alabama or Georgia, learning the basics of whitewater kayaking and/or white water rafting on the Ocoee River in Tennessee! No experience necessary for this adventure of a lifetime!" Thanks a lot!
