I had to dig back in time to find a couple of themes that could perhaps be suitable for this challenge. It is possible that they may be missing the mark regarding the objective of the challenge.
The C&O canal has had a history of problems dealing with the forces of nature even in its heyday. The park that remains today where this canal once operated is particularly vulnerable even to this day, especially since there is little money available to the National Park Service (NPS) to maintain its 184.5 mile stretch along the Potomac river. The aqueducts have suffered damage regularly, and the ones that are still standing are there primarily due to the efforts of volunteer organizations working with the NPS to preserve some of these historic structures.
In 2010 there was a massive snowstorm that hit the Washington DC area and the east coast of the United States called Snowmageddon! Over the next few weeks the melting snow in the mountains caused massive flooding in the Potomac river and a disaster in the C&O canal park. Here are a few pictures showing some of the problems caused by the weather. I am happy to observe that the particular oops! seen below have been addressed over a period of time since that time.
In 2012 we visited West Africa and the country of the Republic of Guinea. We did a lot of traveling while we were there. It was an adventure of sorts considering the conditions of the roads and the vehicles in use. In fact the highway that we took from Guinea to Senegal was essentially a dirt track winding through the mountains. The vehicles on the road were in many cases several decades old, kept running by the ingenuity of the locals. There was really no public transportation available, which led to amazing scenes of people and material stacked in and on decrepit vehicles traveling on the bad roads. In any case, the circumstances were ideal for us to witness many oops! moments. Thankfully we were ourselves not involved in any serious incidents.
