Unfortunately, it's going to be cold and very rainy this weekend. Part of teambuilding will take place outside, so bring warm clothing, a rain jacket and possibly something like sweatpants. I added hot chocolate and whipped cream to the two-meter long shopping list...
Remember to bring a mattress, sleeping bag and most importantly: a pillow. The auditorium benches are unforgiving.
Last but not least: no laptops, tablets or other devices. Just your preparation kit, collected materials and a few pens!
