my photos are taken by me or of me, taken by somebody else
I guess interesting/boring is subjective - can't see anything wrong with rail lines myself.
yes picture posting, as I mentioned a while ago, can be tricky - hard to get the right balance between the absolutely obvious like Sydney opera house or Stonehenge (the UK one!) and so obscure that nobody has a chance.
Post a pic, answer questions to narrow it down if need be, give clues if asked - and lets all enjoy the game ð
