OH WOW! I was 7 yrs old in 1975 so I have no direct memory of it. I was probably too busy with my Barbie dolls to notice(can I be counseled for that?). BUT, a few years ago I made the bad, bad mistake of asking my mom about 1975. My normally very sweet, mild mannered mom became very angry. Needless to say, I didn't get any answers. I learned a lesson that day!
And with the scripture that goes something to the effect of "not even the Son knows the date or time" why would anyone be all fired up about figuring out when exactly the "end" will come?
