I took delivey of my leaf a week ago and live in Thousand Oaks. I was wondering the same and took a round trip to the beach in Port Hueneme. It worked out well.
I started with a 100% charge, no climate control, in eco mode. The path: 101-Las Posas-Hueneme rd. to the Pier at Port Hueneme and back on the same path. I set cruise control to 65mph on the fwy and tried to model the same load while on the farm roads.
The round trip was 52 mi. and there was ~20 mi on the gauge (eco) when I got home.
Conejo grade experience: Regenerated 13 miles going down the grade and lost 17 miles going up for a net loss of 4 miles. How long is the grade? 4 miles round trip sound about right? Not bad! It had plenty of torque to cruise up the grade at 65mph (~40kwh to the motor). The car ran away from 65 going down. I let it run at 70mph+, but touched the brake pedal which pegged regen at 30kw for ~half the downgrade.
For those unfamiliar with this hill, it's a 6% grade.
BTW, the Nissan dealer in T.O. has a couple of L2 chargers and would be happy to let someone charge there. They are great and have sold over 40 Leafs themselves.
My wife works in the San Fernando Valley. I will be testing out that commute soon and can report on that too if you like.
