I've seen the adds for this on TV. and it made me wonder about he people who organize and run such events.
We were in Buenos Aires for the start of last years event. When we took a tour inEastern Patagonia, around the area near Puerto Madyn, our guide told us of the local opposition to this event because of the destruction of roads, fences, the local wildlife and the general ecology and environment. Apparently the locals will not co-operate or partake in the event.
Other parts of Argentina are lke minded. Makes you wonder, does it not.?
