Strange sight.

In the USA, The way I remember which side of the streets are odd numbered addresses is which is closest to Seattle.
Living on Puget Sound in the 70s was neat for a while, but the place was and still is full of "free thinkers".
All federal interstate freeways are numbered leaving San Diego also.

Just taking a mapping test for work, odds are south and west sides of the roads. But like most of the younger generation, maybe he was afraid of commitment, not quite ready to take the plung into Kilts. But it is Seattle there are many a weird site to see in that town.
