I only got 18 miles on that particular trip due to the headwind on the Grapevine. From my front door to Hobie and back it's almost exactly 1000 miles. I fill up with Biodiesel in Santa Cruz, then top off in Santa Barbara, make it to Hobie, load up, then make it to Santa Barbara to top off for the trip home.
The Grapevine is on US 99/I-5. Santa Barbara is on US 101. How do you use both?
