I am not over confident when I ride through area at night. I always check both sides of the bike trails for hidden danger like muggers.
My knife is strapped directly to my packpack that I can easily withdraw it. My head is protect by helmet hence a rock won't damage my skull. I had lots of practice jumping off the bike in emergency. Next time I will buy a steel baton. These muggers will have regular cheap knife which is no match for my 6 inch benchmade tactical knife. I don't want to use weapons unless my life is threaten. I had been serveral serious deadly fights when I was a teenager. My fighting skills might be rusty as I grow older.

Crime in the city is getting worse recently than I ever recall living here.
