I didn't take my laptop on my last trip - a six-day visit to Phoenix - which might not seem like a big deal except I don't own an iphone. Our only phone is a flip phone with no internet access, and being Canadian, it doesn't work in the States. So for six days I was screen-free. Hands-free. Eyes lifted at all times - all five senses tuned in to the world around me.

And do you know what I saw?

A world that wasn't seeing.
