We have purchased the 5x5 pass for the last 12 years. Never ever have they notified us regarding the tier 1 purchase price. It is always sold out. Leaving us to, once again, pay the higher price. You would think being a loyal customer they would notify us when the sale starts. Also, getting far too crowded even on a work day. Bye bye Mount Saint Louis. Skiing somewhere else. You lost us.
