I know when that poll was first put up, our son was also too young (like smokey's). He is 21 now and I think he would consider himself a John Wayne fan still. Maybe it IS time to update the poll. I know I was in a different age bracket back in 2003.
Maybe an idea to make the poll more "timeless" would be to put brackets of birth years instead of age brackets. My birth YEAR won't change over time, but certainly my age bracket will.
