Would be cool to see you over here! As far as climbing goes, there are some places not sooo far away from the Netherlands where you can climb. Can send you some suggestions if you are interested ... Hey, if you are coming over how about slipping one of the 4 way SMD resistors and a soldering bolt in your bag. That's about the only part of the button hack that I'm not sooo keen on trying myself if I don't have to. Would be willing to supplement payment with good German beer
