Well, I’m biased, but I really fucking love the SF skyline in the night. You can just see a hint of it from various places and I just think: that’s my city. :D
On the flip side, there’s an incredible view of a rocky alpine mountain ridge in El Dorado County, CA that you get from a vantage point along SR-88 near Kirkwood. Bloody amazing.
And of course the view of the sky over the Carson Valley from Kingsbury Grade in Nevada will always be on my Top 3 best views of all time.
