When our new maps came out we were told we could work with them on boundaries, etc., but the numbers the computer came up with were not arguable.  The trick is getting the FSA folks to work with you on drawing lines in the right place.

We were also given the opportunity to combine smaller fields into bigger fields ( something we were not able to do in the past even though we farmed it as one field, not as many as 4 as the old maps showed.

We were told to take the time and make sure everything was correct, because we would have to live with it a long time.
