National Parking Day is a way to make people more aware of water conservation and drought-tolerant landscaping.
"I think it needs to be addressed, certainly, and why not address it right here, it's a great place to do it in a tow away zone," says Kathy Cairns of Pasadena.
A sign for National Park Day emphasizes the word, "park" not "parking." The idea is to temporarily turn a parking space into a park.
"Get out of your car, and sit in a park," says Colicchio.
Though, in these situations, they're pretty small parks.
"They can do a little hiking and not get too tired and hopefully not get injured in the process," jokes a passerby.
Parking day tends to eat up a lot of parking spaces, which are usually at a premium in Southern California, but the people Eyewitness News spoke with don't seem to mind too much.
"As long as it's not at a bus stop, I'll be alright," says one Pasadena resident.
No bus stops were turned into parks, and by the end of Friday, all the small parks will be turned back into pavement.
These parks will have served as a fleeting oasis of environmentally friendly, drought-tolerant plants in a sea of glass and steel, and a green beacon of ecological hope.
