Once you feel your body and skill are up to, you can travel directly east from where you are all the way to Americana. There are dirt trails that link that area, but you probably are aware of that. I would take Americana from that area to Annandale Rd. From there your trek is the same.

Your current route might actually be better, but if I had to pick a way to commute with your point A and point B, that's how I'd do it.

That said, you ain't kidding about those parked cars on Americana. I actually lived in a Town House along that street and my god. Americana is a parking lot. I used to commute on it and it was pretty annoying.
