This is near the intersection of St. Mary's and Topple Lane ( a continuation of school st.). Who or what is topple is a question, and why birdhaven? As well I'm not certain as to where the exact stop is, on the north or south side of St. Mary's rd. There's a school on the north, and all that land is developed NOW, but on the south side there is a vacant lot. Then again, judging by the pic, the "station" did not take up that much square footage.
i wish i could put a link for specific map links, such as google maps school st st. mary lafayette california
I'm also guessing it's a line to Moraga
As you can tell, this is all a crap shoot. I'm winging this.
