>>1775139>>1775188I heard it's unlikely that ursacks will be allowed in the Sierra due to personal beef between the market of the ursack and someone high up in California. I can't remember the details though.
For the record I was in RMNP last sept and ursacks have been approved there. Last time I checked it wasn't mentioned on the website but I spoke to the rangers there when I picked up my permit. You have to use it with the aluminium liner though. Still better than a hard sided can.
Funny little story about picking up my permit. I was hiking the pfiffner traverse so needed one for RMNP for my first night, I was going from milner pass to east inlet junction, one of the more modest days on the route. The rangers had flagged up my permit thinking a mistake had been made. So I explained my plans to them and convinced them I knew what I was doing. They eventually came round and have me my permit dating it was the craziest thing they had issued all year! Made me feel like a badass haha
