I like how everyone wants you to dispose of hazardous waste properly but when you call around no one knows where it's supposed to go. I called around ALL day one day trying to figure out where to take some old paint... not one government agency could tell me... so I set it all out to evaporate and sent the dry cans to the dump with the rest of the trash.
Funny though... not one person I talked to could tell me where to properly dispose of hazardous waste.
Typical. Don't trash the enviroment, but, uh, we don't want it either. Kinda like NIMBY (Not In My Back Yard).
That's exactly what our city suggest you do with paint. Our county actually has a good recycling system. In fact, too good cause a lot of our old cars are gone because of it!
Gas is a tough one - I'd ask the fire department.
