I actually liked the fact that they mowed my lawn (i had some last year). They needed almost no feed!! My lawn looks pretty bad without the geese. (Haven't mowed, luckily, the chickens have helped some..but they are in tractors).
However, the spouse REALLY hated the fact that the geese liked taking all naps on the walk to our front door. It was wall to wall goose slime, or
I guess, edge to edge goose slime.
You had me at "mowed the lawn" and lost me at "goose slime"...
