Maybe, if the weather is not too severe. If we see that during your tour time there is potential for lightning, hale, or tornado, we will call off the tour and offer you an alternative date and time. Sometimes we will just delay the start time by 30 minutes. If we are unable to provide an alternate time, we offer a full refund or issue gift certificates that do not expire. We know Minnesota weather is unpredictable, but we can tell you that on an average season we cancel fewer than 20 times out of several hundred scheduled tours.
