Hey Wotto,
Before going on my trip, l checked out two of your forum threads were you posted your holiday diary. Was disappointed I didn't get to see Vince Neil or his tattoo parlor though! Haha

I wouldn't go out of my way to fly to Chicago for Pinball Expo on my next trip as I have done it once and it's a big distance to get there. The Stern tour and expo as a whole made it worthwhile for the pinhead though. The Stern tour made me want to own a Stern machine. That's a pretty good achievement I reckon!

Can't remember roughly how many machines in the games hall, but in my YouTube videos I go down all the aisles with my camera. I think I was disappointed as I only got half an hour at the hall of fame in Vegas and expected to play various machines at expo and then discovered they weren't there.

Going by your previous photos, I definitely want to go to Pacific Pinball Expo.
