YEs Acusa is in SA, its in the hill sjust out of naine.
Probally been there since the late 30's in various forms and now is owned by MA.SA and has an enduro loop, a long track, a scrambble track and a mx loop.
only has 2 rounds of Dt and i think the rest of the time its club use or Ride days ( public) open days, because its volunteers who keep the tracks tidy it can be prity rough and unkept.
i think one of the guys from levis was grading it yeary but im not sure of that. GO MA, then link to the SA site and you will see Acusa park map. its nothing special but its all we have :O)
