The length of it would make it pretty good for sand, I imagine. I'm currently in Antarctica and there is simply no soil. It's ice I can't get a stake into or rocks. I use a "sand anchor" (or snow anchor) and put a stone in the pouch. It works OK but not great. I have to MacGyver a better hook to keep the handles from getting tangled. Ideas?
Pictures please! Add them to the "flying your rev in famous places" thread. I'm pretty sure there are no other shots of Revs in Antarctica.
Could you sew a velcro loop onto the anchor bag, and then loop that around the ends of the handles? You can get velcro at your local Walmart . . . oh wait

Just kidding. Got a carabiner? I sometimes clip the handles to my kite bag with a carabiner if I don't have a stake handy. If there's a handle on the anchor, you can clip the carabiner to that.
