While technically allowed, there's not really a good place to properly attach an Ursack at Trail Camp and you're at risk of having marmots or other critters chew through your expensive bear resistant fabric. The bear fabric is not designed to hold up to those small critter teeth. There are trees at Outpost Camp, but it's such a short hike to OC you might consider a hard sided canister if you're camping there.
This is where I tend to go with the hard sided canister - in heavily used areas with a history of bear problems. Not so sure Whitney meets the second criteria, but I choose my small BearVault for Whitney. Wish I had the small Bearikade - are you listening, Santa?
