Our family "collects" Major League ballparks, trying to attend a game at as many parks as we can. After experiencing delays getting through security at Mile High Stadium last summer because of our camera bag and our tote bags, I looked for a way to speed things up and came upon this clear bag. I ordered one when my daughters were planning their first game of this season, to test it out.  I was pleased to hear that the quality was quite sturdy enough for the purpose and it was well-made. So they got through security faster thanks to this, and I will be ordering one or two more.  Given the security procedures we encounter, this seems like a simple and easy tool to speed the process. I recommend it.
