This tour link the Atlantic airfield Block Island with the Pacific airfield Friday Harbor. Has 17 legs. I’ve done it with my beloved C310R (an image of the route is shown here).
The routes were made with SkyVector also the charts are from this site. The Ravalli / Hamilton aerodrome KHRF (wrongly identified as 6S5 on MSFS 2020) has a VOR to VOR route chart made by me.
The tour is intended to be made with a light airplane without GPS. VFR and VOR / NDB navigation is encouraged.
