This is a simple concept.
You purchase a ticket to go to an event.
You have (hopefully) a good time.
You leave and you have a ticket stub in your pocket or purse.
What do you do with it?
Well, if you can scan it, post the picture of the stub,
you can also share your story of the event at this blog.
As Andrew Taylor writes:
"It's clear from reading just a few entries that these are moments that define people's lives, and that the ticket stubs are markers of personal history. What a fabulous way to invite the world to share those markers. "
So if you really wanted to go to that (you fill in the blank) event, maybe someone else did and you can share what they experienced.
Certainly, I would encourage you to share your own experiences with your ticket stubs.
Thanks to Andrew for the link.
