Next time, make sure not to put the piles of mulch right on the course were the trail needs to be . We had to work twice: first moving it out of the way, put the cardboard down and then pile it up on the cardboard.
On other locations in the park it was better thought, with big piles of mulch CLOSE to the trail, but not ON it.
We were also ran out of cold water. Plan to have more coolers available.
I got to help out cleaning around heritage trees in the grounds of the Norwood bungalow.
