Some of the worst selfies I've ever seen are at Auschwitz or Ground Zero.

Huntington Beach is like ground zero for surfers.

Ground zero for me is audio.

Zero ground is the beginning... sometimes you just don't have the normal productivity day.

I really think that education is ground zero for fixing anything.

When I was a kid, I went from ground zero to Pluto. The first place I played was the Houston Astrodome.
