We have one at the "dump" and at the city facility. At the dump, they use everything that the trucks pick up. That includes dead animals on the side of the road. If you can get past that and wear gloves when you spread it, it is very good compost.
The "dump," or waste disposal facility does charge a nominal fee. The city facility doesn't charge.
We also have a spot at the botanical garden that shreds Xmas trees each year. You can back up to the pile and load as much as you can carry, but it needs to mellow before using it.
