Secret map

 Here's a secret.  Some time last year, I was taking Geography of the City.  This is at University of Washington in Seattle.  At one point the professor put some different exampled of street layouts, grid, near a factory.  And one was like this one.  Labeled suburban development.  I don't think this prof had been in Sacramento before.  It wasn't this one exactly but it showed the same.  Don't try to read the names.  I look at the projected map.  I haven't lived in this development since 1964.  But I had looked at it lately as traveled down for our 50th but held in our 52nd year.  I had been impressed with Castec Drive.  Kind a large semi-circle in the middle.  Hey, this one has a semi circle.  Waida minute, this edges of the semi crcle could connect to the street La Sierra Drive that ran through the whole development.  And those streets at the bottom.  That could be Los Molinas.

What?  I was looking at Arden Park in suburban Sacramento.  Where I lived until I was 12.  I know a lot of the names of the streets.  I could put an 'x' and my parents house.  But I don't know how.

What were the chances?
