I'm only guessing, but I believe the city is responsible for the soccer field, and most likely, they keep them locked away until a coach nerds them for games or practice. Maybe even from being stolen, so they don't have to replace them. Just my opinion.
They remove the goals so they can insure they will be there the next time.
No idea. I guess they're only up for when there are games being played. It was disappointing to take my son out there and all the goals were gone.
