30 years ago, my neighbor got his brothers to put a new roof on his house while he was at work. The brothers bought two colors of asphalt roofing shingles, and spelled out the word "HI" in letters about 25 feet high. I lived higher up the hill, and could plainly see the prank. Their excuse was that they wanted to make sure that any 747 pilots flying past would know that friendly people lived in the house. Some time later, (I recall it to be years later) the owner had enough of the questions about his roof, and PAINTED the entire roof a different colour. I wonder how much paint asphalt shingles will soak up? I bet it's an awful lot.

Disneyland feels sooo much bigger as a kid than it looks on the map.
