My North Fort Worth community pool had their spring pool/block party this past Saturday night. They also hired a DJ but as far as I know there was no trouble. The flier stated that it was for residents only which I understood to mean NO GUESTS!

I bet a lot of HOA’s are reviewing their rules right now, about bringing guests to the common area/ pool.
