I cannot say for certain that the 7' line is sacrosanct, but it does seem to satisfy goose 'needs'. I arrived at that amount of land because what I was creating on the golf course was a 'hazzard' from which golfers could choose to possibly fashion a swing and hit an errant ball if they wished. I would not use boulders as this gives the birds a perch to land upon and then hop off into the yard. Planting shrubs/thorny roses along the inside of the fence provides comfortable nesting areas for the birds in the spring with no access to the water for the young. It would be possible to develop a perennial garden along the 100' using only plants which are cut to the ground in the fall to discourage nesting. Using plants that take up a lot of space and planting in large drifts with an eye to always having something in bloom is an interesting project. Spring bulbs to peonies to butterfly bush to the lower growing perennial sunflowers to perennial asters...these sorts of blooming progressions. The New England Forum people should be able to help you with ideas for easy care, clumping plants that are cut back in the fall. Your problem does not have easy solutions. BTW, I tried using low wire fencing instead of the fishing line idea and it did not work too well. I surmise that it is the surprise element of bumping into the unseen line that discourages the birds.

That IS cool.

Dixie, we went to FL in January,and found a winter place while we were there. We came home, got some stuff ready, and then went back for almost 2 months. Juanita, we got home (here in MN) last week. Been playing catch-up for a while!

What lush scenery! It almost presents itself in layers. The geese really enhance the shot.
