Yeah, lay on a creeper or a piece of cardboard so you can slide around and look for discoloration. Better yet, take a screwdriver and tap... don't dig and you'll find out if the floor is solid, or mushy in places. A piece of chalk to outline the mushy parts (I hope you don't find any!) will help in if/when you need/want to replace part of the floor... if you need ideas on how to "mark" that from the top, let us know.
