Not a safety day anymore

one family live only 4 people in the house brother, sister, mom and dad. Sister she ask if we can go to the claim mountain today  because the weather is not bad at all not too cold not too hot. Dad say that is not a bad idea because the kids are having a long holiday. so they go to shopping for the climbing mountain shoes and all the safety items. They went back home to packed everything and get ready for tomorrow. When every one ready something wrong happens ... as the weather change, they ... cant go and more because it not safety.
