Thanks Rick.It looks like if I just go to the TOPO software and create a route everything should work out OK. I have 61 waypoints for the 27 miles and the Garmin will take 250 points so I should be able to even navigate the route where the trail is not a direct track between waypoints. I do have the track from the original trip so I know where the trail goes on the map even if there are no recorded waypoints. Obviously map and compass is less hassle.
