Wintersun,
I've been up and down 395... and posted pictures. I apparently never had any trouble getting diesel... but then I always fill the tank.
I can then feel comfortable... knowing that some where in the next 450 miles there will be a station with diesel pumps.
If I was buying $10 woth at I time I guess that it might be a problem... are you filling your tank? What is your range with a full tank of diesel?
I seriously doubt that there is a place in North America that doesn't have diesel... do you have any idea how many pieces of equipment run on diesel... how many commercial trucks run on diesel?
I have bought diesel in Monterey too!
California isn't that backward...
