Livestock on the beach??

I walk on the beach  each day before work…and frequently see people with dogs.  But a pig?  There was a young man on the 101st Street beach this morning walking his pig!  It was a large, pot bellied pig – on a leash.  I asked the young man holding the leash if he lived here…and he said his family was vacationing from Pennsylvania, and brought along the pig.  I didn’t have the nerve to ask if they were renting with a “pigs permitted” clause in their lease!
