 In this assignment, you will plan, carry out and report on a data walk. Each student will submit **a brief report** (around 600 words) with supporting materials such as maps, photographs and notes taken en route.
 
 During the walk, you will focus on _data hubs_: objects or sites that collect data. Examples include customer loyalty cards, ATMs, traffic cameras, RIFD tracking systems, OV chip card scanners, QR codes, parking meters, air quality meters, but the list could go on and on.
 
-Under "normal circumstances" a data walk would involve a small group of 6--8 people taking on different roles, such as navigator, note-taker or photographer. For the purposes of this assignment, you should only involve one other person, such as a roommate or family member. Plan your walk someplace convenient, for instance in your own neighborhood, and restrict it to about one hour. You may also ride by bike, but we advise not to drive unless you or your participant is unable to be mobile in other ways.

 Your report should address the planning, execution and your reflection on the data walk. You may take the following points as a guide as you complete the assignment:
 
 1. **Plan your walking route ahead of time.** Make a map or list some landmarks you intend to pass on your walk.
 2. **What will you look for?** Which data hubs do you expect to encounter along the way?
