Although the Ursack is not legal in the parks, it is a good alternative to a second canister. Your legal option is an extra 2 pound canister and at a 1 more of pack to handle it. I'd take the chance for an Ursack for a day or two chancing fine.

I've seen a ranger once in the SEKI backcountry since 1997 and that was a seasonal ranger, not LE.
