I have done that before as well, I didn’t realize it till afterwards because they were all bedded. She was at 75 and everything else (2 dozen) was closer but hidden by topography. She tasted great but tough as all get out, every piece.Don't shoot the only mature cow with a bunch of calves, that is the Nanna cow and she can be tough as shoe leather, found out last year.
She did have interesting whistlers though.
