Well I just got back from the train ride gig, indeed one of the most bizarre experiences ever.

Wow I feel like I was surfing for 3 hours, oh yeah I learned that lashing things down is very important. Also that I really like the horn blowing at road crossings, it almost works in an odd way in most keys thanks to the loud tri-tone horn. LOL
I enjoyed watching the guitar player trying to use his Wah pedal, hilarious, he came very close to tipping over more than a few times.
Also watching the drunken folks trying to walk and dance in the isles was more than entertaining.
I would recommend it for anyone that doesn't have motion issues, I thought our drummer was going to hurl, he doesn't even do roller coasters, he was a bit green looking the first set.

But he toughed it out and once it got dark and the train reversed direction he was able to deal.
I've only got 3 gigs I haven't done left, submarine, space ship and airplane, I somehow don't think I'll ever get to do those, but then again I would have never imagined playing on a train.
