About the surprises, I looked in my history to spot the few surprises I got during ski days in the last 16 years.
As I was more skiing in the real trails until 1997 (except in few areas of the Laurentians), I didn't got real surprises until that year.
So I got 8 surprises in 292 "official" ski days.
I could say 10000 words about every one of them, but as nobody would read them (lol), this is just the facts.
April 2, 97 : discovering Chevreuil on a off-piste expedition nowhere in particular.
Dec 20, 98 : looking up on my 2nd ride up at Val St-Come, I found just in front of my face the monster Pins Rouges. (I literally cried of surprise)
Jan 29, 2000 : Heard about lines between Maxi and Grande Coulee. By chance, I found Ecureuil on a first shot... this simply changed my life

lol
Jan 4, 2001 : Going down Contour, I've seen in the middle some snowcat tracks !!???? I followed the path and when I stopped (to not hike), I miraculously found back Chevreuil. (I thought the icestorm destroyed it or that it was Passe de l'Ours) (here, I cried... and a lot !)
March 4, 2001 : I found that what I discovered 2 months before was just the lower part of Chevreuil... and to find the place I skied the best run of my life 4 years before was probably for me the biggest surprise of my life, overall.
March 4, 2001 : Trying to find the entrance of Chevreuil... I found Porc-Épic on my last run of the day... I didn't know what to think and was becoming mad, so went back 4 days later to understand the place. I found the entrance on march 8, but it's just on april 14 of the same year that I completely understood how Chevreuil was designed !
March 4, 2002 : 1 year later, it was at Alta, in horrible conditions, but I found by chance an incredible brand new trail that affected me so much that Alta became back my #1 best ski area that day, 5 years later...
March 8, 2002 : Massif du Sud, 1 year later again... I knew few trails were not on map... but I wouldn't ever had thought to find a trail like #8 !!
You're certainly right about the incredible lines in Vermont... and for the surprises, with an average of 1 ski surprise by 2 years and only 4 ski areas where I got a real surprise, it's something really rare. For the lines, theoretically, you're right, although practically, it's not the case in QC. Tremblant almost have nothing, same thing for Le Massif. Ste-Anne doesn't look so good for that. Alta (656) and Avila (600) are quite better than them. (although you may remove the "really long" I admit). The longest one at Avila is over ½ mile long and is pretty hairy, but the numerous ones of Alta are less long in general.
About your comments, Patrick. After my university, it will be the tax income period, in april, so that's a month where I won't probably have the time to ski a lot and certainly not to do trips in the west.
May could be better... with Sunshine and Lake Louise still open in the beginning of the month.
Europe simply doesn't interest me at all for now... May be at 35 or 40, it will look more interesting for me... gonna see that.
And for Stowe, 90$ for few trails don't interest me, unless they're more than really, really, really, really interesting. Tremblant's CBC is my 6th best trail and I'd not skied it since 2000 before this year. The only reason why I went there this year is that I got a free lift ticket. I will never encourage a ski area that charge so much for a ski day.
