After the 1910 file in northern Idaho, the FS and the the CCCs built literaly thousands of miles of pack trails for future access for fire control. Many of us maintained those trails between high school and college graduation. In the 70s the trails came off the FS fire budget and was replaced with helispots. That was followed by the let it burn policy.
There are a lot places you can 't get to without those trails. Consequently we have learned that trail maintenance is part of our requirement if we want to access our favorite areas.
I don't worry about overuse because the majority of people are terrified of leaving any developed transportation systems let alone leaving their vehicle of choice.
In most cases I'm within 2 miles of a maintained road and have only cut tracks of humans 4 times in 40 years. If your human density is higher than that, you likely need to be reconning other areas.
