**I always got that it "COULD" be our generation. **
I believe it was Jack Chick in one of his pamphlets that boldly said the return of christ would "BE IN YOUR LIFETIME"!
Consider the source.
I also heard Chuck Smith of Calvary Chapel use the 1948 date and the fig tree as a starting point.
I've researched Smith's statement. It was properly modified for those who were listening.
