"I'm illegal in the Winds (I can't hang food because I can't throw due to shoulder issue"
Mary D, I had a ripped rotator cuff on my last big trip, and I used a rock sack, that's a tiny stuff sack you attach to the bear bag hanging line, you whirl it around a few times then let it fly, it works. z packs was selling those, not sure if he still does, easy to make too, any nylon, it's just a 2x3" stuff sack basically.
I had no problem getting it over high up branches, took a few attempts, but I never had to use any extension at all on my shoulder, which was a good thing, since I didn't have any.
The idea is simple, you spin the bag with rock in with a few feet of cord, then once it reaches the right angle/speed, you let it fly, sort of like a sling shot in some ways, it really works. Still in my opinion the greatest backpacking innovation I've ever seen.
Ursack needs to fix their website, it's too hard to find all the knot diagrams, they have them scattered around, and users of the bags not knowing how to do the knots was I believe one of the issues, that is, you can miss-tie the knots, but you cannot really mis screw on a bearvault lid.
To me this is pretty valid, ursack needs to improve and simplify their website and bag documentation for knot tying, I have the green one, and it doesn't show how to do the figure 8 knot you use to attach it. I have no idea why they still have not rectified such a trivial thing to fix, one more knot diagram, and all knot instructions on one page always accessible from one click on their main menu, not cut in half as it is now, where you have to know the other one is there to find it. I should have emailed them about that issue, it's kind of hard to take them seriously about usability when they can't fix that simple thing on their website and bag.
I also hope they get approved, but I don't think it will happen as long as they depend on such a non robust knotting system that can fail if users dont' do it right. I guess the white bag makes t easier now from what I read, less stiff so it's easier to close, but that's the third try now, easy to see why parks who don't want problems chose not to allow it. At least easy for me to see. And they actually admit that without seam grip the bear could get into the bag, so you really can't consider skepticism about this product as unwarranted. How do you test for user ability to tie a knot? And to always tie it right and tight enough? And to have applied the now included seam grip? Compared to all cannisters, which work and are sealed as soon as you close them, I have no trouble seeing why they aren't allowed. Too bad you can't get a license that proves you know how to use it, since it appears that when used correctly it's quite effective. ie, ranger stops you, sees ursack, asks for your permit/license showing proficiency, then says, ok, thanks have a nice trip.
