maybe a dumb questions but....

when does the ski season begin in Colorado and in Tahoe?

when is there usually a good/decent base?

should one wait at least a month after it opens to go?

I usually go in Late Jan to Early March so there is usually plenty of snow-
I have always been lucky to actually have good conditions- powder, sunny,
etc.... I am thinking about going earlier this year, however, I do not want
to be dodging rocks.
