With this resolve, Katti thought of having an environmental event that would mainly feature a bike ride and a march that would converge at the Quezon City Memorial Circle. That was in 1999. She then contacted a few friends from the Cycling Advocates (CYCAD), Philippine Daily Inquirer and the UP Mountaineers. (P.S. The march I proposed to be organized by the UP Mountaineers didn't happen because they were busy with organizing the federation climb that year.)
With the help of her friends from various environmental organizations, the biking event was soon under way. Katti notes how she was always encouraged by Ramon Fernan III, CYCAD's president, to continue with the project in spite of her being a neophyte in events organizing.
When plans were already underway, the only problem was how to call the event. Katti brought this up with Lorie Tan of Bookmark and president/executive director of the World Wide Life Fund Philippines. Lorie suggested to use the adage "When was the last time you saw fireflies in the city?"
The idea clicked well with Katti and she brought that up to Mon Fernan, who likewise picked up the suggestion.
"Fireflies are indicators of the balance in ecology. The reason why we don't see fireflies anymore is because the air is really dirty. Hindi na sapat 'yung mga puno, 'yung tubig. Doon mo kasi mahahanap ang mga fireflies sa ganung klaseng lugar (Trees and clean water are not enough. That's where you'll be able to find fireflies in places like that.)."
