I'll go first...
None of this is intended to be scheduled like an organized ride, just a rough idea of a plan:
PCH, Ortega Hwy, Santiago Canyon Road (Maybe)
, Adams & Magnolia, Fountain Valley (before 8AM)
via. PCH & Ortega Hwy
Planes of Fame Museum
, Chino Airport (the lunch-time goal)
(if we don't get sucked into the Airplane Museum all afternoon).
We may not get to all of these places this weekend, because it's not intended to be organized (so enjoy the fact you were out for a good ride, regardless of who you might have missed).
