An independent filmmaker has followed several adult skaters through their training, trials and tribulations. Those include health, family and career issues, including military service.

The filmmaker is trying to raise money to complete and issue the film. Alison Manley (Manleywoman skatecast) vouched for the creator, so I think it's probably legit, if you want to make a donation. If not, the trailer is very thought-provoking, so enjoy it!
