There was someone moving out along Shelburne Shoal off the point by the buoy today...I was sitting in my office wishing I could be plugging holes out there off Proctor Shoal.
That said - I access the Burlington Marina pretty easy but again that pressure crack takes some navigation skills. Easiest way looks to be from Shelburne Bay Launch as suggested above if your using wheels and by wheels I mean 4 wheeler only and even I am not that crazy. The ice makes so much noise in front of Burlington it will make a veteran pucker. lol
Last I checked I walked all the way to Juniper>Shelburne Shoal>Back to Burlington Marina, 2-3 weeks ago and there was 12 plus in spots.
Good luck - I will be in this area and maybe try lone rock point if its a nice day for a walk .
