Can you reuse Heavenly Lift tickets @ Lake Tahoe ?

Me and my friends are short on cash, and only had the cash to snowboard for 1 day due to the extremely overpriced lift tickets. I noticed before you enter the lifts they scan the tickets, but they do not mark them. On the lift tickets they put the period of validity on it, but not the specific date you need to use them on. So I was wondering if you could just use your lift ticket again, would be a cheecky little trick to pull but these prices are ******* ridiculous.
