The DGAC (Director General of Civil Aviation, the equivalent of our FAA) had a warehouse at the airport. There was a small soccer/basketball court next to the warehouse. They told us we could have anything we wanted. We took their basketball equipment and all their park benches.
This picture was when we'd just started, but when we finished setting up, we had equipment all over the benches and mounted all over those basketball "towers".
Oh - See the windows on the white building? You'll see the other side of those windows in the next shot.
