Reach out to your local fire department (esp. if a volunteer dept) for knot training use. It wouldn't get used to people, but would allow them to set up rigging without worrying about damaging they real rope.

I keep some around for use at the campsite to hang things, or secure things if needed. No life safety stuff of course, but it's still handy to have around.

Finally finding time to have adventures instead of waiting for time.
