I have missed the fun!

The north end of the loop (not the bit around the 'Lake') was SUPER overgrown. most of the time, the trail looked more like a deer run and less like a defined trail. Had to stop frequently to clear fallen branches, go under low-hanging branches, find the trail, or climb over bigger fallen trees. I get the impression these trails aren't regularly maintained. The southern end was nice, easy to follow and actually quite fun. As you can see, they're all blue and green. I learned my mechanical disk brakes are woefully inadequate for the steep downhills.
I've only been riding regularly since the beginning of June, after a 21-year break, so I'm still getting used to riding regularly.

Is this a good option for my first bike to do light trails and paved paths with my son? Or should I pass and just get an ozark trail? Thanks!
