Recycling

We have curb-side recycling here in Carson. I always thought that as long as the item had a triangle with a number on the bottom that that meant the item could go into the recycling bin. Recently someone told that I should check with my city to see what numbers they accept, that the city only takes certain numbers. So I did. After much searching, I found this:

Acceptable Items
Notes
Aluminum Cans
Glass Bottles & Jars
Magazines
Newspapers
Plastic Bottles
Steel Cans

Not exactly helpful. So I guess I'll call to be sure that I'm not putting items into the bin that don't belong there. It seems that this info should be readily available on the Internet. Or maybe I just expect too much from my local sanitation department.
