I ran into a friend yesterday who has been following #mappingedges through Instagram. Although he lives only 10 km away, because of traffic, poor public transport connection, and generally busy lives, we barely see each other and he hasn’t been able to join any of our walks. He had noticed the images of papayas growing on Marrickville’s edges and wanted to know if they were the kind that were good in Som Tam, Green Papaya Salad (https://en.wikipedia.org/wiki/Green_papaya_salad).
