I've set up some sort of climbing apparatus, as if in my grandma's garage. A line stretches from inside the garage out to the street, with a lot of carabiners that slide along it, like a shower curtain.

I'm trying to secure the system for when I'm not around. I slide the beeners down to one end, but I'm concerned that they might be stolen. I consider taking the beeners off the line, but it seems like a lot of work for every time I want to use it. Hmmm.
