I haven't seen many or any posts about this on here so I thought I would start one. Most sets are fairly easy, but I am sure most of us have seen sets, or at least parts of sets that were kind of hard. I started this thread, so of course I have a personal example :-)
For me the numbers for the date on the fire brigade were a pain in the rear....Building them is not so bad, but building them so they are all straight and look good...well, that's another story. I think I even cussed a little on this one. So I am anxious to hear if this or any other part gave anyone else a hassle or two.
