A few years ago I organized an outdoor team building event in the fields and forests near the lake Balaton. It was really exciting, teams were given 4WD Jeeps and they had to navigate from station to station using some blind maps and radio instructions.
One of the tasks was crossing a river with an old bridge on it. The bridge was in awful condition, even I had concerns about crossing it on foot, and going across by a heavy car seemed impossible. But we had really smart engineers and tech guys in all teams, so we provided some materials for them to repair the bridge and make it stronger.
We were waiting for the teams to arrive when on the other side some unexpected guests arrived: a herd of cows from the nearby village wanted to march home peacefully. They were as surprised as we were, there is usually no one on the other side when they have their usual daily walk home... they were cautious and stopped in front of the bridge. But then the bravest stepped on it and the others started to follow slowly.
I was so excited - the cars could have arrived in any minute and I was afraid that the cows would be frightened and would not go home... But finally, it all turned out well: the cows marched away and in a few minutes we heard the cars arriving. Huh, it was a relief... The guys repaired the bridge, so from then on the cows could trespass safely.
Conclusion: when you prepare such programmes, you should consider other factors besides the human ones... There might be animals using the territory you plan to "invade"... :-)))
