Further to my previous msg, I've found some historical snow reports on
http://www.skiclub.co.uk and they indicate that late March/early April
are best. I know that the amount of snow required for good
skiing/boarding depends from resort to resort (i.e. some resorts can
get away with less snow than others) but do you know if Whistler needs
a lot to be good?

Once again, many thanks for your help
