I have also created a Virtual O at Pontiac Lake, starting from the Horseman's Campground, off MaceDay Rd. Same idea as Maybury.
No flags, no streamers, download the Usynligo app, print the map, run the course, app will advise you when near the control, captures your splits. (And if you choose to enable the setting under your profile called Store Trace, you can export a .gpx file for import to Livelox.)
