I've spent a lot of time around those hinterlands, although a long time ago (thankfully). How were the skeeters and blackflies? I actually got sick once from too many bites. It felt something like a bad hangover.
Our timing was excellent: water levels were just right and we mostly ahead of the bugs. There were two nights near the end when the mossies and black flies were mildly annoying. Coming was a different story - worst bug season in recent memory!
