Wade,

I have fields that run from 3 acres to 130 acres. The longest rows are 7/8 of a mile. My pass to pass is good, but I do have to "shift" every now and then when I come back to a field.

I am right between 2 CORS stations. I have one to the west of me I would guess about 40 miles (I am not sure of the exact location of the station). The one that I use is 30 miles east of me at the farthermost location. This might be a good location for a VRS between the two stations.
