No, I don't know how, and I no longer have it on the internet. However, it could be found. Basically, United was touting Tebow over the Steelers on their gate location screens at the Denver Airport. It surprised me that they would allow that at the airport. I hope someone will find it and post it.
Actually this was pretty easy. I googled United Airlines gate signs Denver or something like that. When I found the picture, I right clicked on it, chose copy, went to reply on this thread site, put the cursor on the page, right clicked again , and chose paste.
I usually have trouble embedding pictures, though.
