Bicycles on our sidewalks remains a very confusing issue to me.  I am now 68 yo and am quite concerned when walking sidewalks in the Ala Moana neighborhoods, especially when walking on sidewalks along Kalakaua, Kapiolani & Ala Moana Blvd.  Approx. 6 years ago I was hit by a bicycle on my left arm and elbow.  The bicyclist in this instant was young and hit me from behind; gave me the finger and called me a f&%*ing haole.  I didn't think much of it other than being really miffed at the young man, but I did not realize it caused nerve damage and I continue having tangling/numbness in my left hand fingers.  Now I'm older and I constantly feel I am dodging bicycles when walking on the sidewalks.  I consider all of these streets/sidewalks as being in the "business districts" as in the definition of our city bicycle laws, however, there are many, many bicyclists riding on the sidewalks in these areas.  I guess my only recourse, should I be hit again, is hire a lawyer and sue the city.
