I had no pond to cross. Just some artificial line, where the colour of the officials uniforms change.On that trip I had the pleasure of not seeing any officials other than the ticket checker. So far as I know unused glass is not an issue in europe.
It's great to see this thread still entertaining. The bong is still being appreciated on a daily basis, and since my last visit in november I've added a nice ROOR ash catcher w/diffuser![]()
