Interesting data about humidity. You are an encyclopedia Simon!

For once, I feel I am lucky compared to EU citizens.  In Buenos Aires
(Argentina), humidity is continously at a range of 50% to 75%...  so far I
haven“t experieced any problems with any of my instruments (well, maybe the
guitar and bouzouki/mandola strings get rusty a bit faster than when I stay
in Sweden :P)

It would be a good idea to compile all this wisdom somehow in the gurdypedia
or an actual book, like "hurdy gurdy, as taught by those who CAN play it" :D

cheers and keep it up.
