i commuted downtown for a conference on mild traumatic brain injury at the Hilton, which I have to say had a very nice parking area for bicycles underground. Most Toronto underground lots have a well lit and watched area set aside for bikes. Anyways, hearing the longstanding cognitive defects possible with even apparently minor accidents involving closed head injury is enought to make one paranoid. Good thing I had a helmet or I would have never heard the end of it from the MDs.
