In case you haven't been getting any invitations to any activities from Discovery Land/Spanish Oaks, this will solve the mystery:
You aren't a member!
Right. The Golf Club haves are invited. The non-member have nots are not.
No more S.O. activities for have nots.
Wonder who will be allowed into the ol' fishing hole?
It would be nice if this were communicated from someone 'in charge', but maybe only the haves got the word.
