After about a year we decided to expand the Coop. Design on Sketchup again.
The member who was a builder got busy (good for him, bad for us) but we had a bit of money and hired some carpenters to put together the frames for us.
Then we drilled, t-nutted, put up and painted the panels ourselves as before.
Matting was extended as before and the remaining mattresses were gotten rid of.
We also built a training area at the end (for wads training and everyone else injuring themselves...)
