Believe it or not, I've never made it to Eagle Lake. Never even made it to Antelope. Best I've managed is a few trips to Frenchman - but then, it's not that far a drive, either.
Furthest north I've managed has been Susanville, except for a couple of trips to Redding. And I agree, once you start getting into the mountains it's gorgeous. Kind of makes me wish it was 200 years ago and I was going through there on horseback (shades of 'The Mountain Men' or 'Jeremiah Johnson'!!).
