In my column about tourist destinations and travel spots planning to turn out lights for this Saturday’s Earth Day event, there are two (so far) airports.

But don’t be alarmed – there is no plan to put anyone in harm’s way by turning off important runway or tower lights.

Toronto’s Pearson International Airport, which participated in the event last year, will turn off many of the indoor and outdoor signs, some lights in the terminals and many of the moving walkways.

At Los Angeles International Airport, the focus will be on the iconic 100-foot tall colorful light pylons that illuminate the airport entrance and serve as a backdrop for many film and TV scenes. The pylons will be lit solid green for 60 minutes before Earth Hour and then be turned off completely for the event.

Here’s a link to the full story, which has a description of how all the lights will go out on the Las Vegas Strip including, for the first time ever, the “Welcome to Las Vegas” sign.
