Hanging clothes to dry in MN fall + another tarp question

[TominMN]

I use dyneema line and truckers hitches, zero hardware. Which then makes me wonder why I don't just do that on the ridge lines too.

Because now you see a good reason for not stressing the ridge of the fly.

You could use the trucker's hitch on a single ridge line and use Prusiks with soft shackles as tensioners, a la Dutch, as a no-hardware approach.
