Here is my updated master map showing the path of every walk I've taken since 2009. I'm now up to 619.5 miles walked of the approximate 1000 miles of SF city streets. This means I'm solidly over the 1/2 way mark. I am super close to knocking out the Outer Sunset, so this will be the focus of my next walk which will hopefully be THIS WEEKEND while I'm up in the City for work! Wish me luck (and time) to cross this huge neighborhood off my list.
