I've found out that my trip to Michigan's UP will be camping at sites with either bear lockers or trees suitable for hanging bags. After reading some BF touring threads and looking on-line, I've seen Rat Sacks, Outsaks and Grubsacks. None of the stores in my area carry any in stock so I'll ask you, the experienced touring campers for your opinions. I'll couple any of these three with Opsaks. I know that bear bags (i.e. Ursaks) are used, but the metal bags seem to be more rodent resistant.

Thank you.
