      This is indeed my first bivy. Your comments are valuable and plan on making many of the
      changes you suggest. I may not be able to comment much about the intricacies of the
      material (I'm not as knowledgeable in this area), other than how well it performed. I'll
      make the changes as soon as I can, but that may not be for a day or so given my schedule.
      I may just have to meld yours and the official editor's comments together.
