My garage is old. My Grandfather and my Dad built it back in the day, for a Model A Ford. These days, I have to be careful about what kind of vehicle I buy. It can't be too long, or it won't fit in the garage.
Anyways, sturdy as it is, it's sagging a little in the middle. This means that, try as they did, the guys who put the gutters up a couple of years ago, couldn't get them to drain completely. That sag in the middle stops the water from flowing every time.
This Mourning Dove, in spite of having three separate spots in my yard whereshe can get nice, fresh water, always seems to prefer the yucky old stuff that pools in the gutters.
