Sergio explaining how to use the equipment to concentrated Yoshi.

Bruno thinking of going up (la que me espera!).	Ey, that's me climbing! No fear, Carslten is there to hold the rope if I slip and anyway it is an easy wall.

Yoshi having fun in extreme climbing (well, some minutes later he showed us he was the gifted padawan of Master Sergio and climbed once and again, once and again).
