hammocks are actually amazing for your back! if you want to learn more I highly suggest going to /r/hammocks. Very friendly and active subreddit. If I were to suggest a cheap, easy, foolproof set up. i'd do this. Hammock, Straps, people may say go with the kammok roo python straps, but some parks are super choosy on what can be hung on their trees. And heres a tarp that regularly gets down to $20 on woot.com.

Damn, do you think the Grand trunk Navy one is worth it at $68? https://www.amazon.com/Grand-Trunk-Skeeter-Beeter-Hammock/dp/B001AIFLX2/ref=as_li_ss_tl?ie=UTF8&qid=1477930787&sr=8-1&keywords=Grand+Trunk+Skeeter+Beeter+Pro%3Cbr%20/%3E%20%3Cbr%20/%3E%20+Mosquito+Hammock&&linkCode=ll1&tag=gearhosecom-20&linkId=73c13334b87d9d4a8ed7d69b23718213

It has a bug net, is it worth the extra cost?
