I just re-read this post in preparation for the next big tarp set-up test.
And you know what, I'm actually looking forward to it!
I got my new ropes with wooden tensioners and springs. I didn't buy new poles - am just taking my 4 old wingnut ones, but my friend is bringing her new ones.
We'll set it up in the morning on the second day, so we have plenty of time. And we're staying for 2 weeks, so it'll be totally worth it.
I'll let you know how I went and what I learnt!
