Last Sunday afternoon (4th October) I climbed on Ostrva (Mengusovska valley) and I forgot to bring there my chalk-sack. After the first pitch of route AKL I asked two polish climbers (who had climbed Dieskov kut and were rappeling down the same route) if they could lend me their chalk-sack for the second pitch of AKL and wait for me an hour down under the wall untill I finish it and rappel down, so that I could give it back to them. They were very kind and lent me their chalk-sack with no hasitation, but they didn't wait for me to give it back to them. I would like to ask them, if they read this message, to contact me on my e-mail address miroslav.peto(a)seznam.cz
