Hello,
I think Ladera is on the other side of the 5. The climb on Oso and Crown Valley go to Nellie Gail and LN. And yes, there are many hills in South OC to kill FE. As I think about it, there are hills off Oso and CV going thru MV but being a single occupant vehicle the HCH is pretty nimble around all those SUVs there.
