Barry , In my little world I would probably take a chain saw to quickly cut things to size, cutting out the steel to dispose of later and if you have a bunch of nails in boards (depending on the amount and how soon this had to be cleaned up) I always enlist my kids with hammers, crow bars, sledge they love it, well kinda?? They are 12 (twin boys) Once ya get them going that is...
If any of the wood is still straight or useable for a small future project, at my place a trebuchet comes to mind...Busy kids...
For the spoils when I burn I have a two row cinder block circle that contains the fire with a couple big sitting logs next to "fire ring" and we usually roast marshmellows or just have a bonfire...something to do with the kids...
There are always some branches, twigs, etc. in the fire ring... If no kids are around it can still be done... Just an idea
