I looked it up out curiosity, it's over 2 miles along a major road that crosses a major freeway. There is a suburban route that has a dedicated bike lane crossing of the freeway (101). Yikes.
This sounds exactly like the sort of walk my wife and I end up doing when abroad. "Doesn't look that far on the map. Let's just walk it, get our steps up. It'll be fun!" End up choking on fumes the entire way...
