Sierra Nevada,
It is very obvious that FS and NP are biased against Ursack. I happened to be at Kearsarge Lakes when Bear Vault had one of their problems. A Ranger told us to put our canisters in the bear boxes because 7 Bear Vault canisters had been compromised.
The Park Service worked with Bear Vault, then there was Rae Lakes where "a bear" figured out how to open their canisters. The Park Service, again, chose to work with Bear Vault to rectify the problem. I have not seen this type of cooperation with Ursack when problems occur.
As I have stated, I do not follow the Inyo's rules/recommendations on how to use an Ursack because they are nonsensical. I tie it off in a tree 4' to 5' off the ground to keep the elfin bears away from it and for stealth. I don't need no stinking chippie chewing through the fabric to get to my oatmeal and gorp.
