The increasing popularity of applications that share location information over the internet enables the mapping of people's pictures and activities. Such applications often focus on the now, ignoring the importance of places and stories from the past. Inspired by recent work in HCI around reminiscing, in this paper we present a study in which 16 people used Google My Maps to write about their past, using place as a trigger for memories. People had a wide variety of strategies for choosing which places they remembered and the stories they told about those places; on balance they liked the idea of using maps as a tool for reminiscing, suggesting that this is a promising line of inquiry for further work.
