Thanks for the dimensions, BB. I was wondering about this very thing this weekend. Between my Explorer and 2 Scouts ( for my 10 and 7 year old boys) I have ended up with both a brown and green "hex fly" plus the stock tarps. Using Brian's suggested suspension method of one end secured to the tree and the other on the hammock suspension line, there is definately some play and room for adjustment. Gues I'll have to hang them all at the same time to see which tarp works best with any one hammock. Makes me think about mixing and matching. Hmmm.
