Wood for campfires

Starting camping again after being away from it years has presented us with new guidelines, rules and regulations.
The one that I need to deal with now is about getting firewood for campfires. I am coming across the rules in most states about transporting firewood in from across the state line and even from sections of the same state.
My question is thus, how are our members dealing with the forewood situations? If you buy it at the campground you might get a few hours for $7-10. I have evev read somewhere that there are camper and campsite checks here and there for illegal wood.
Also I have noticed restrictions for "constuction" materials. I am not sure of the makeup of items included in this forbidden list and wonder if my short pieces of pine, popular and oak that accumulated after a project constuction are banned also?
