My Camino is getting closer ( start on the 29th of April) and of course am now mulling all sorts of things around in my head. Do I need a pack liner? I read some where that a good quality small garbage/bin bag with a pull tie would suffice for clothes or should I buy a liner/liners. I am using small zip lock plastic bags for my toiletries etc. I am starting to worry as I just read the posting below about rain jacket or poncho and I am taking a rain jacket and rain pants but read how the rain can go between my backpack and rain jacket if the rain is particularly heavy. I am not going to go out and buy a poncho now but thought I might have to do something to prevent the things in my back pack from getting wet. Thanks!
