"They really don't approach something like a an UrSack with an open mind."
Yeah, and I'm not entirely sure that's wrong. People- not we, just people in general- are uninformed about the outdoors and don't take the hazards or LNT very seriously.
As I was coming out of the mountains a few weeks ago around 8PM, I was asked by two people whether the trail was flat or steep. I responded that it was a bit of both, but I also mentioned that they should be careful because this was in very active bear (black and griz) territory and that bears are most active around dawn and dusk, and were known to frequent the developed areas around the lake the trail goes to. They laughed at me and walked down the trail with flip flops on, with no water, in shorts and tank tops at dusk. They didn't exactly strike me as UL types...
Unfortunately the agencies need to shoot for the lowest common denominator. There's nothing stopping people from buying an Ursack, tying a mouse in the top and leaving hanging from their tent smeared with bacon grease.
Wow, thread drift. Maybe we should move this over...
Edit: I think the Ursack is awesome, and I want one, but I can see how the angencies are skeptical of its general application.
