Again, here is the messaging about weather:
Brrr.... the forecast looks cold for Sunday. Don't worry, we've done this plenty of times! The check-in area is LARGE and heated. We have outdoor patio heaters, and there are plenty of warms stores for you to duck into if you like. The ceremony will be outdoors, but you will not be outside for long. We promise the photos are worth it! Should there be a blizzard, we of course, have a plan B and plan C. You will know about any change in plans in advance. Our indoor back-up location is the 6,500 sq ft space we are using for check-in. It's beautiful!
Stay healthy, dress warm. See you soon!
