I admit. I'm cheating.
I took photos every day in the conference. I just did not like any I took on day 3. So this photo is taken in day 2 after few (or a few more) drinks with friends and colleagues. However, it is my challenge, so I'll allow it.
The conference venue was centered aroun this beautiful dam. With clear skies, amazing number of stars and a slight glow of town lights from nearby, the scene was just beautiful.
