Path Track is sometimes perfect

Jon is relentlessly using his iPhone Path Track ap. I am impressed by the quality of some of the "tracks" it captures. Yesterday evening we walked in a hurry before the rain in Reynolda Gardens. The Path Track record of our walk is very accurate. This is far superior to my original idea of using a fine-point black Sharpie on my laminated map of Winston-Salem. Here's the link to this track:
