For a group of gentlemen who have an obsessive interest in collecting small things with holes in them, you're being mightily bold.
For many years the only way I could survive an INS convention was to spend an inordinate amount of time in the hotel bar.. but these days, since that activity is imposed upon by collectors wanting their dirty netsuke cleaned.. I'm forced to find other escapes.
So it was in Cologne.. luckily for me, a small woodland right next to the hotel had a resident Nightingale which gave me many hours of listening joy and peace... well it did until a homeless man who also occupied that little woodland decide that listening to "his" Nightingale required that I forfeit a few Euro. He as quite insistent or so it seemed as he barked commands at me in German... so I gave him the money but the joy was lost.
So I went up the road and saw another wonderful thing in Cologne.. an island of unused land next to a major road that had been densely seeded with wild flowers... with hundreds of bees and beautiful butterflies taking advantage of the banquet.. it was quite magical.
.. but then it got dark so I went back to the hotel bar.
