A Fellow Angeleno
I also live in LA, on the West side. So far I haven't seen a single other Rocket on the road; only at the dealer. I bought mine last August at Southbay Triumph. I've got about 4500 miles on it, trouble free, and mostly on the daily commute downtown and back. This is by far the most exciting bike I've ever owned.
I've added the Windvest screen and I really like it. I also have the short backrest and sissy bar, and two extra clocks - the clock and the fuel gauge. I'm about to add an alarm, Icon shocks, and the pullback bars. At 155 lbs, I find the OEM shocks do nothing but propel me out of the seat on every non-trivial bump in the road.
Best of luck with yours. Maybe we'll spot each other on the road.
