I remember around 10-12 years ago my son had a birthday party at our house and one of the children's fathers asked how long we had lived here. We told him and he replied "OK, I was pretty sure this house looked familiar: I built your stone fireplace. You have some boulder retaining walls out back, don't you? I built those too." The pride on his face, finally getting to meet the homeowner and show off his work, was amazing.

The cool thing about bricks and rock is that those walls will probably be there 100 years from now.
