I went out without my phone this afternoon, ended up in a bar and then outside some more. No phone on me.
It also reminded me of the good old days of going out on long walks with my Canon 7D DSLR on me and perhaps a MP3 player, instead of just carrying this machine called 'smart'phone that we use for everything. It's still possible ;^)
Would be nice to see a post on those events!
For a while now when I'm outside I really ignore my phone, I don't even listen to music with it. I just much prefer to look around and hear all the sounds. It makes me feel much more present, in the moment. Actually living and moving. It feels much more liberating, like you said in the good old days with that simplicity. The weird side to it though is realising you're the only one not glued to a screen at all times.
