It's large easily 400+ houses with other surrounding neighborhoods.
Sergio stated two signs one on Princeton Place Dr. and the other on Huffsmith Kuykendahl (Note: youtubers it is pronounced kur ken doll; a running joke in Houston if you can't pronounce it you're not from here),
My neighborhood is small and people do the same thing re: advertising and signage. Actually, around here you are lucky if someone doesn't throw your sign away. We have neighborhood "sign police" out this way.

Ironically while looking I noticed the cedar walk house was just listed for sale again.
