Perhaps the greatest thing that happened the caving summer 2006 was my meeting with the Polish cavers from Sekcja Taternictwa Jaskiniowego KW Kraków STJ, with Karolina Filipczak leading the group. Unfortunately her accident in Tjorve put an end of her caving that year, but I learnt to know some nice people and skilfull cavers. I also promised to visit Karolina and Kraków later that year, which I did. That great week-end visit resulted in a small text, that can be read here!
