I didn't include an address, but a Google search with "green day ashby house" will give it to you. I included it since no member of Green Day lives there and more people know about it as opposed to the Armstrong house. Should there be a "no private residences" rule? I don't care either way. I'll remove it for now.
In other map news, The Ruby Room has been found and added to the map. However, I cannot find the exact location of Fiat Music as the directions put the placemark in the middle of the street, and I can't identify the building in street view mode. If anyone can help, please do. I also adjusted the placemark at Christie Rd. to show the area where people hang out.
I feel like no private addresses should be a thing. It's kinda awkward. I would just settle for Ashby Street, and if someone wanted to drive down and see- so be it, but no actual address.
As far as Fiat Music, I can't give you the exact address because I don't know it, but I do know it's in a plaza in Pinole Valley. There's also a Walgreens, and a Subway, and stuff in said plaza. IT's really nearby the high school.
Wait! You can see a number in the picture I took of the place. I would try searching that number and Pinole, maybe it'll give you something... not in the street.
