We had an uncharacteristically warm and long fall last year, which was amazing, but...climate change, y'know? We are anticipating a warm and long fall again this year and, while back-up plans are in the backs of our minds, we do not expect snowfall during this weekend. It will, however, be chillier in the evening as temperatures typically drop down to the 40's. Additionally, the ceremony itself will be held outside and the ground will not be paved despite being well-maintained. You will not need to walk up the side of the mountain to get to the ceremony site, but we would caution against wearing incredibly high heels.
