Progress continues.  The floor in the dining room/kitchen area has always sloped, likely due to the dining room being an addition. A few years back we had a professional foundation company come out and ensure that the foundation and flooring in the addition is okay.  They added some supports but the floor has still been sloped.  We went ahead and pulled up all the old wood flooring and underlayment.  Was a little scary to walk on, luckily it was only this way for one day/night. 

New plywood, will provide much more level underlayment for the new wood flooring.  We were very happy to have actual floor to walk on again.
