I called on this today. He said that it is his uncle's lumber and he is getting out of the lumber business. Some of the details I gathered:
Widths: varies, 4-12"
Thickness: varies, 4/4 - 16/4
Lengths: 10-14'
Air Dried for "several years"
He said that he wants to get rid of all of it, but would be willing to break it up (just not 1 or 2 boards here and there). I asked him to check the minimum bd ft he would be willing to sell and expect to hear back from him in the next day or so. Also, price may vary from the ad depending on qty.
If he is willing to sell in ~ 100 bd ft qty's I plan on taking a trip over to see it and will post some pics and more info.
