Hi all!

I inherited about 21 gallon cans, and 18 quart cans of paint with the house when we bought it last May. I knew there was some paint in the shop building, but I had no idea there was this much. I've not been successfull in finding a government disposal day. There is one where we used to live, once a year, but it always fell on a weekend we were out of town. We now live in an unincorporated area, and I'm not sure who to call to see if the county has this available. On another thread, it was talked about opening the cans to let the paint dry out naturally, then they could be disposed of. Many of the cans I have are already dried out, one is so rusted my finger poked through the side moving it one day.
My question: How many cans can I safely open to dry out at one time? I have moved them to a separate storage building, even away from my shop. But I don't want to overload things. Thanks for any help you can provide. Jim
