Hi,
Welcome to the forum, there are quite a few roadies close to you but quite a few seem to be quiting for the winter. I guess they prefer their turbo trainers! Search the forum for cycling in switzerland there are a few really good threads. Not sure if the temprature is going to plumet but it has been pretty mild November so far. I cycle most days but I am down in Geneva, not sure there is a bad part of Switzerland for cycling.
