Personally, I like creating tracks on my 64s - I pay for 7min topo detail and overlay OnX ...so it's a great tool. With a track, I can navigate around thickets, to specific creek crossings, and no one besides me knows.
I do like creating a track (if it's a known spot) since a 'direct shot' from parking is not always the best route to take due to obstacles.
If you can follow tacks, safety pins or other ...so can everyone else.
I will place three tacks (rotated around the tree) at hunting height on a kill tree so when I get close, I can find the tree and set up more easily in the dark.
