I've put most of the Loops and shortcuts in proud lake up on Google Map Maker now... If any of you guys using Google mapmaker you can approve my edits and hopefull soon we will see the loops on google maps ( much of loop 4 should be showing already - see link below for loop 4 )https://firstname.lastname@example.org,-83.58338,2261m/data=!3m1!1e3
Once approved loops 1 - 3 and many of the shortcuts should also be showing too.
This will hopefully allow someone to pull out their smartphone on the trail and see their exact location on the map and see the trail at the same time.
If your not familiar, google allows you and me to make changes to the maps we see when your are looking at maps.google.com
you can add trails and roads and etc.
