As promised I have now posted in the "Files" section of the website several ski trips that I know of that are being promoted by local non-profit ski/sports/social clubs.
For all of the trips one needs to be a member of an organization posted at www.midwestfun.org.
The cost for membership in these organizations is cheap, and range from $10 to $30. You more than get your money back by the discount lift tickets you can get through these organizations on daily, weekend or longer ski events.
Doesn't hurt to check out the flyers posted. FYI- I signed up for the "Ski Stimulus Package."
