Wow dude, that is cool looking. Just never ever try and bring that thing through any U.S. airport. They will take you somewhere even GPS can't track. ;D

I thought about that. Wouldn't be wise to take it on a european flight either. It'll will be even funnier if they ask you to open it and you'll have to explain that you can't - at least not there :slight_smile:
