Re: Any climbing/"drinking" mate?
On Friday evening I wll go to the gym and meet some friends at 20:00 at Volta Bräu (http://www.voltabraeu.ch/). You are welcome to join us there.
I could show you the main sights of Basel on Saturday, at around 13:00.
In the evening you could go to a burlesque show (http://www.weloveburlesque.ch/english/next-show/) (I am not sure yet, if I am going myself but friends of mine are going...).
On Sunday, you could visit the Fasnacht (carnival) in Laufen at 14:00. The Basler Fasnacht starts a week later 22nd with the Kienbesen on the 21st and is the better choice.
