Where can I dispose of coolant (legally)

[6T9PONY]

In my town, the City provides each household with recycle bins. One for paper, one for plastic, and one for glass. They also will provide you with a container for used oil. Every Friday morning you put the bins out on your front sidewalk and they come around with their trailer and dump it all in there. What I usually do with my old antifreeze is mix it with some used oil and put it in the used oil container. I know you're probably not supposed to do that, but they won't notice when they're dumping it and they'll have no idea it was me! Plus this whole service from the City is free, so it works out great! I don't know if they do that in many other towns...maybe just in smaller ones like mine (Pop. 6,200)...
