Francis Spinoy, a Belgian caver who was active in the Swiss Sieben-Hengste network since 1970, is currently producing some nice Powerpoint presentations, mostly from its old slides (which were scanned at least). The text is in french… but an image is an image, isn’t it ?
The first one has just been released, and you can get it simply by sending him a mail at : fspinoy@gmail.com Just add in your mail the following comment : “Please send me your Sieben Hengste Powerpoint presentations”. More will follow soon.
