Well... 3 hours slogging around a baking hot golf course isn't exactly for light weights...

But contact these guys http://www.baselbaggers.com/home.html they're a bunch of friendly english speaking expats of varying degrees of ineptitude

they mostly play in the Alsace as it's a bit cheaper and easier to organise

even then, it's expensive.. reckon on around 80 to 100chfs for an afternoon's entertainment

(oh, and if you're serious, I would recommend looking for your gear at either Athleticum in Dreispitz or maybe one of the big french sports supermarkets near mulhouse)
