are there any stretches through here where one can not camp?

at a rough preliminary glance, i'm considering camping at davis path campsite, somewhere around lick creek (mile 562), hunting camp creek (mile 579), someplace in the vicinity of va 611 (mile 599), watipi shelter (obvious this one is ok i would think) the "campsite and spring" at mile 632, possibly pine swamp branch shelter, though if i can stop 2-3 miles before that'd be ideal, the "stream" at mile 669 (may just do laurel creek if the prior night does end up being pine swamp), and this last one may be trickiest- somewhere between niday and pickle branch shelters. in essence, trying to split the distance between 669 and VA 311 roughly in half. i have a feeling that might not be legal.
