I'm headed to Switzerland for 3 weeks (May 23rd to June 12th). I'm headed there for a learning abroad session. I will be staying right outside Zurich. Most of the schedule is fairly well set, but I do have Saturday afternoons till Monday Morning open. I want to head over to France and ride the highspeed rail there one day, but other than than I'm looking for some things to do around Zurich, or within a day trip from there. Any ideas?
