Yes! The free section for my city is the best, I've gotten some walnut and some maple.
Another good source for me has been noticing trees being taken down in peoples front yards by tree services. They are only too happy to have some of their load taken away for them, and a couple of the chainsaw guys have split the log sections lengthwise through the pith for me. I have some sycamore roughed out and drying from one right now.
