Or...
The developer/contractor/ designer of the project paid the freight for the trip.
A paid press Junket if you will.
Stations news departments used to have some pretty solid journalistic rules about such junkets and who paid for them.
However with the erosion of journalistic rules (and skills) , it's easy for stations to accept all kinds of freebies or cross promotions that blurr the lines of objectivity.
"Oh it's newsworthy because our local Congressman/ Mayor etc.. will be touring also."
That's how they (Managing Editors, and ND's ) justify the trip to feel better in their own minds that it's gonna be a total ,"fluff piece".
For Example...
"The Disneyland/ Disney World WX Live Shots Back Home".
Every station falls for this one...
(but the viewers luv 'em)
Your local station sends your weatherman to do a a wx live shot with Mickey, Goofy and friends....live from the Magic Kingdom.
Disney provides the entire set-up....the camera ,sat-time, the photog, the field producer and even Mickey and a few princesses or animated fish. Disney puts you, and your kids and spouse into a free room and gives the kids free tickets while your local Weather-Schmoo fills 4 minutes in the C and F block of the newscast.
!00% free promotion disguised as your local weathercast.
It's even more fun during ratings when the park is filled with wx dudes and dudettes from all over the country doing shots back to home.
Disney can handle a whole bunch of those shots...and have a million ways to feed all those shots.
All you need to do is... (Insert Your Hometown WX man here)
