I alternate between these two. Both of which I took. The first is the Golden Gate Bridge (San Fran) from a few thousand feet up. Could only grab a quick pick with my iPhone (4), I really which I had been able to get my DSLR out to take a better pic, but we were coming in to land.
The second I took at BMW Welt (BMW World, Munich, Germany) when I toured the museum there. Definitely one for BMW fans
