An immense barbecue demanded an immense downpour, of course. But we saw it coming, and bought ourselves an immense gazebo. This took an immense amount of time to build, during which we got immensely soaked.
The barbecue was fun, though less immense than I expected. It turns out humans can only consume about 30% of the amount of food I thought they could. This leaves us with a whole farmyard's worth of meat stocked in our fridge and freezer.
The gazebo is still standing. I refuse to take it down. Anything that demanded that much time and effort to build I classify as a permanent structure.
