Might be game... If I ever get my in' bike back!!!
Another option for a Saturday trip would be go to
Gurten
One of the blokes I work with goes to both fairly regularly. From what I hear Gurten is a bit better (depending on what you prefer!), more dirt trails, whereas Filzbach is more gravel type stuff...
But then again I want to do
this so I shouldn't be thinking of too much lift assisted mountain biking... especially now with pretty much 2 weeks off my bike behind me!!!
