I was holding off on saying whether I'd turn up or not - this being out of Lausanne meant I had to be a bit more cautious about promises, since it necessary involves more time than simply Metro-ing into town would. As it turns out I had to do laundry at the hostel through the day today, meaning I didn't get back into work until about 8pm, so didn't finish until 10:30, and I think that would have been a bit too late.
Hope there was a good turnout in the end. See you all next time if in Lausanne. If not then, well, I will try!
