Backup rope?

[MGLion]

I wear one of these http://www.survivalstraps.com/patrio...-multicam.html for emergencies.

I have a spare tarp RL made from 2.2 Lash-it. ~30' long.
I mostly use it for a clothsline but would cut it if needed.

I have a small amount of 1.75mm Zing-it in my first aid kit, along with many other things I never/rarely use. I'm guessing 10-15'. Not much but better than nothing. I don't carry it for any specific reason.

I always bring some paracord. I can make due with it in just about any situation.
