Hey Mossback, I think we may have the same map....perhaps the same outfitter.  Back in 2009, I went through This Man and camped on Cheatan Bay...only because it was too late in the day to go find another camp.  My map is marked with a very cool 'secret campsite' on a point on the SE shoreline just past the small oblong island on the same shoreline.  I was told it had what could be described as improvements of the nature that Boy Scouts used to build - pioneering type stuff...counter type table, etc.  While we did find evidence that it once may have been very nice, it was way over grown, not very big or open, tons of mosquitoes and in my opinion, is better kept a secret and that was 7 years ago.  It should be easy to find - there is an eagle sitting in the big white pine just above the campsite.   ;D  We did find a suitable site on the western of the two long points coming from the north shore, if memory serves me, however, I would not seek that one out either.  I don't think many people spend much time in that bay.  I was told there is good lake trout fishing among the reefs just through the narrows, but have no experience to validate it.  To me, it was not worth the paddle back up in there.  If you decide to head that way, I'd recommend you do it early enough in the day to check it out good and still have time to back out to the main lake if you don't find it amenable.
