Yes, typo
Then you've guessed it first! Good job with noticing that rappelling gear :) Yes, it was a helicopter rappel training on that day :) Those were joint exercises organised by Kielce's SPAP for SPAP members from all over Poland, firemen from Special High-altitude Rescue Group and soldiers from an airborne battalion. In later days they were also practicing descent into watercrafts, jumping into the water from a helicopter, rescuing people from the water, etc.
Johnny_reb, were you in the military?
Miloslaw and jon357, you were to some extent onto something too, because they may wear those T-shirts also during competitions, but johnny_reb guessed it right!
Thanks everyone for participating, I had fun with this one :D
Yup, you and Miło were both right :) It used to be one village before 1920
Wow, that's amazing :D
@Delph, yes, that was an interesting riddle and a difficult one - I'm in total awe that Milo and dolno guessed it! When you gave those statistics I figured that it may be in Zaolzie area. And I liked your clue at the beginning - it was almost poetic :)))
a symbol associated with the legend of the foundation of Kielce? Kiełek is the name of the wild boar monument in Kielce.
Yes, exactly! :)) A wild boar is one of symbols of Kielce because of this legend :)
@Dolno, do you want more border crossings or more riddles? ;D
