1/26/13 UPDATE: I left a message at Prairie Dairy Farm across the road to get the address of our old farm & current owner's phone so I can learn when old barn torn down, etc. They don't open until Monday. I
I've been searching all over county roads with only numbers for several days, but finally asked my cousin to help me. This is where the old farm is per MJ:
"I found the the farm on South County Road 1000E. It is south of Old National Road 40. Rd. 75 crosses Rd. 40 north of the farm. At that corner, going south from the old station/restaurant on the corner are two houses across the road from one another. The first one is on the east side of the road (Prairie Farms Dairy), then next is the one on the west side of the road which is where our grandparents lived. The place across the road is where we used to rent and live in the Wilson (at that time) house. I am sure they didn't have postings of the road numbers and directions then.
It has been ages since I have been down that road and more buildings have been built, but I can see the old landscape and going on south, find the same roads leading to where we lived on the farm on the hill. It is on East County Road 450 South, after going across the creek. A creek runs on each side of the property. "
My landmark had been the old Phillips 66 station on US 40 going to Greencastle where Grandma Parker caught the Greyhound to Decatur. I recently found & scanned that pho which I took in 1970 on a family history hunt. It is all gone now of course but MJ says the McCammack family owned it. A larger overview of the Parker farm in context is below the Phillips 66 pho and would help for anyone trying to find it again using MJ's directions as well as their own farm (Tressman & Fern Parker, parents). A street view is not available on Goole Earth but I found a Birdseye view on Homes.com. The dairy's address is 2785 S. County Rd 1000 E, Coatesville IN 46121 (phone 317-539-5326). On Trulia, it is listed as being built in 1922. The Parker farm is marked with the red pointer A. Google lists it in Putnam, IN but Trulia lists it in Coatesville.
