The only thing I'm sure about in this album is the first photo. Matt noted the date, place and event on the front of the photo. I wish he would have done that for all the photos. It would have made things a whole lot easier. I'm including the other photos because scenes match or people match (same clothes from one photo to another) or decor matches.
We held a number of meetings in Knoxville over the years and have used the same motels on many occasions so the decor may or may not be a valid item of determination. So if you can place any photo at another location let me know.
