BETHEL - Almost 46 years after the Woodstock Music & Arts Festival burst onto the quiet hills of Max Yasgur's farm and defined a generation, Mysteryland USA lured a new generation of revelers again to the legendary grounds.Back in 1969, rain was the major weather feature the crowd had to deal with for the three-day "Aquarian Exposition" that brought 400,000 to what's now the home of Bethel Woods Center for the Arts.
