Came across this map of the Hansen Dam Norton Club ride. You are going to have to wait until November 2016 for the 37th annual but, if you are ever in L.A. and want to get a taste of canyon riding, try this loop. Its a good one and about 75 miles long. When I was a Los Angelino I would never miss it. Nice gathering of L.A.'s Brit Bike crowd. ( and many others).
