Both are showing closing dates of April 14th on their website. Are conditions already pretty sketchy at BC? I went to Vail/BC in mid-march last year when conditions sucked so I guess it cant be worse than that, lol.
No way to know for sure. If the weather keeps up like it is now.... conditions will be great. If it gets warm it will be spring skiing (icy in the am and mashed potatoes in the pm). Get a magic 8 ball... it will be just as accurate as any of us at predicting the conditions.
