I see at several front yard gardens in my neighborhood, plastic 1/2

Each is filled with clear liquid, probably just water. I see so many

I am located in Panorama City, CA at zip 91402.

Sounds like what you're seeing are inverted 2 liter plastic beverage
bottles with "Aqua Spikes" attached... these water plants slowly like
drip watering and their flow rate is adjustable:http://www.amazon.com/Aqua-Cone-Spik.../dp/B001ESSJOQ

There is an urban myth that water-filled plastic jugs spaced
strategically along the edges of the garden will keep dogs from
entering and/or peeing on vulnerable plants. It is not an uncommon
practice in suburban areas but there really is no scientific basis
behind the theory. I'd bet good money this is what's going on with
your 'plantings' of plastic bottles or jugs.

Never heard that one but I fill up containers with water and let them
sit in the sun to evaporate the chemicals in the city water. I
usually leave them out 24 hours. Learned it from a neighbor - made
sense to me. Maybe that's what your neighbors are doing.
