I'd like to find about 50-60ft (10-11mm) of mountain climbing rope for use as long lines (for ground driving). Anybody know where I might look to find some used and therefore cheap? Since my life doesn't depend on it, I really don't care if it's taken a hard fall or gotten wet or whatever else makes it unsuitable for it's intended use. I've looked on eBay and googled, but haven't found anything useful- maybe I'm searching the wrong terms...
This isn't really related to your question - but yesterday my friend (a horse person) mentioned that one day she was hiking in the woods and came upon a rock climbing group that was using a donkey to pull them up the side of the mountain. They had rigged up a system where they would use the donkey to help them up and then they would repel down.
I just found it funny to find a rock climbing thread and thought it would be probably the only time I could mention it and keep it somehow horse related.
The rope at home supplies stores that looks slightly like climbing rope is not the same thing and snags very easily. The beauty about climbing rope for long lines is it is snag-free. I usually just get the ready made long lines from climbing rope from Schneider's http://www.sstack.com/shopping/produ...=1&keyword=mcr
Putting the word out in the climbing community that you will pay some $$ for "retired" ropes might get you what you want at a fair price. Once ropes have sustained a certain number of falls, or been in use a length of time, or had asymmetries felt in the core, smart programs and individuals will retire those ropes.
College outing clubs, adventure programs, local REI or outdoor stores with notice boards would be places to look.
