I PM'd but since it looks like I can link to external trip reports, here is some info on SHT hikes that I did last year, and a trip I did with my son and daughter to Kings Canyon National Park. My hiking trips

The SHT is a great trail and should be a fantastic experience with your son.

I would recommend limiting the miles each day, explore the shorter 'spur' trails that lead to really great views, and enjoy the trip!!

I used the Superior Hiking Shuttle for transportation. I parked my truck at my exit point and took the shuttle to my starting point.
