I am a fossil from the ancient days. In the ‘70s we had a staff of 6 or 7 including secretaries and mail room help. The editor of The Water Skier doubled as PR man. His task was to feed info to local news outlets. He could not guarantee that they picked up on the feed. We had no advertising budget to promote events directly.
USA Water Ski is an affiliate federation of IWWF and the US Team is its property, so there certainly should be a motivation to promote the event.
Visit Central Florida has been an event sponsor in the past and promoted the event. Ironically, Visit Central Florida is a creature of Polk County government and the event takes place in Lake County. Might be one reason why advertising is limited.
