Why doesn't the Pacific NW have glass soda bottle deposit programs?

The last I knew, the midwest still did this. The NW is known for being ‘green’ and recycle friendly. So why then, don’t we have the glass bottles? I personally think everything tastes better from glass.
I’ve heard rumors recently of the possibility of stopping sales of plastic water bottles because too few people recycle and our landfills are getting overrun with them. Charging a deposit fee for a glass bottle encourages people to recycle.
