I was there the first three weekends in April, but I missed the last two.  They have a TON of snow.  The last weekend I was there it was slushy and sick, really fun up high.  The lower stuff was like glue, but the top stuff was really fun to ski.  I wanted to go this weekend, but I have an actuary exam on May 18, so I won't get up until then, which is really killing me with how good it is.  I will probably hit it that weekend, and then Memorial Day, and then call it a season, as our ski lease will be done.
There is so much snow, that the top steeps(most of them anyway) should be in play for a long time.  The Paranoids should be good into June, I would think.  They are going until July 4th, and things should be good in the morning in June.
