I used an Ursack on my last tour as a liner for my front food pannier. It does add a bit of bulk but it effectively kept raccoons and rodents out of my food. I'd just tie it to picnic table or tree without hanging. So far no bear test as seen in manufacturer's videos. I used to borrow neighbor's car trunk or store it in the bath facility if wildlife seemed a threat. Much more convenient having everything close in the morning. Manufacturer gives diagram of simple knot that bear cannot untie with closure tight enough that rodents can't enter.
