Couldn't get tickets for the Vancouver AC/DC concert but my amazing wife got me one for Tacoma, and it turned out to be well worth the drive.
The band was unbelieveable (again, it was my fourth time seeing them), and afterward a small group of us hung out by the security gate and after a while, they let us in to meet Angus Young. The guy has been my guitar hero since I was 14, so suffice to say it was a huge thrill for me. I could tell he was exhausted after the two-hour concert, but he was nice and friendly to everyone and stayed around for almost an hour until everyone who wanted to meet him got their chance.
And yes, he is small. I'm only 5' 7" tall so that gives you some idea...
The 'thumbs up' thing made me laugh. He seemed to do it in every picture and when he did I seemed to follow suit without realizing it -- until afterward.
