Sea Isle City - Sea Isle City VFW Post refuses to recognize some veterans or their family members for membership. I come from a Vietnam Veteran father who was in the Navy. I was told that because I had no physical evidence my father served on land in a foreign country- Vietnam(Served on a ship) I could not join as an associate member. I guess sending 16" rounds into Vietnam jungles isn't good enough for the Sea Isle VFW.
