In general I have my wallet with me, so no problems with keeping the id with me. But I run, generally with another person, so I don't carry ID. A few weeks ago on Bowen path there were a fair number of police, and they were stopping people asking for ID--generally non-running, young Chinese males. Curious, if I were stopped and did not have my ID when running: What would happen? Would this be a major issue, or would they be fine to accompany me home to see my HKID?
