For I 50ft wall I think you would need two 51ft ladders or 1 51ft ladder and a 55ft rope with a brick at the end.
I don't know much about Mexico but I have been there, but I don't know why so many are poor. Does Mexico have a poor economy, do they lack in agriculture production, is the government lazy, or do they not have any important resources that could improve the lives of the people of Mexico? I think America should increase aid and buisness to Mexico. When I went there everyone was nice and always smiling. I went to the town of China and there may be alot of shacks and old homes, but the people there have some nice cars and some nice clothing. I know Americans help in there, but these are no more than church groups going down there to build a church or homes for a poor village. Nothing wrong with that, but we need to get to the problem of Mexico and help them out. They love there country, but for some reason they are just not making enough money to want to live there.
