I live in Columbus, Ohio. My daughter will be attending summer camp for the first time at 4215 E. Landry Lane, Marshall, IN 47859. The travel notice from the camp says:
I have no way of verifying it until the week after next, but it would be nice to be able to use Waze to get to camp (and let the camp know, that Waze can be trusted).
I believe you are correct about the turn restriction causing the issue. I have fixed the turn restriction along with adding a place point for Camp Nageela Midwest - Marshall
You should be able to search for Camp Nageela Midwest - Marshall and it will take you right to the location
EDIT: I have also added a HN for 4215 Landry Ln. If you can, test both to see if they work. You can then let the camp know that they can tell visitors to search for the camp in Waze and should be directed to correct location.
