I went to Folsom Europe in Berlin a few weeks ago, just Friday to Monday, but that covered the busiest part.
The weather was pretty wonderful, I met lots of people I knew and met quite a few people I knew online from Instagram etc. I was in gear all weekend and smoked a few big cigars, a good time was had.
I think what really makes these events for me is meeting friends and making new friends, I enjoyed that very much.
