Back Packing

OK so months ago Mark and his friend where going to go back packing but things came up and they couldn't go. Then they decided to go this Monday and Tuesday they have to rent snow shoes and pack warm clothing. It is like Christmas eve around here he is so excited. I didn't think it was still on with being gone all last week with the funerals and all but he is has Tuesday off and is going. So what should I do for fun?
