Mike, there are several places to visit to gather your Data: The Rock Store, Mount Palomar, Lookout at Ortega hwy, Cooks Corner all come to mind. There are many Charity rides in the Basin.
I was born in Lynwood, CA when it was still a nice place, lived in Downey, Bellflower, Paramount and lastly Hemet and was involved with the bike scene from 1962 until 1999, with various clubs spanning all types of bikes, from competitive off-road racing to touring, all over the States and old Mexico.
My riding now is mostly 200 mile or so day trips, in the beautiful heartland of the Ozarks, riding Everything from Super sport bikes, to touring bikes, to Dual sport/ adventure bikes, with some muscle bikes, like my recently sold 2012 Triumph Rocket 3 Roadster and 2012 Goldwing. Recently I've found the almost perfect bike for me and the kind of "Smell the roses" type of riding I enjoy now, a 2016 Suzuki DL650 Adventure bike.
By the way, my offices were in the financial district of Los Angeles for many years! I only miss a few things about LA: Jewish delicatessen's and REAL Mexican food
