I feel confident saying that you will have to leave the house to meet strangers. Now I'm not telling you to hop on a Harely with a guy sporting a skull and crossbones tattoo and a roach clip. If you are visiting Cape May from another locale, you really can't help but meet strangers. Another year could pass and you could still be telling those same old stories. Take advantage of what is around you.
Local communities have all sorts of social events during the summer.
Go to those in your own town. Drop by those in other towns. Welcome drop-ins in your own town. Ask them questions. Find out about their interests.
