What is the primary concern for Sara during the holidays?

The primary concern for Sara during the holidays is that the area where she lives experiences harsh winters. This likely implies that the challenging winter weather can create several difficulties, such as travel disruptions, safety concerns, or an overall unpleasant holiday experience due to cold temperatures and possibly heavy snowfall. Understanding that harsh winters can impact daily life during the holidays helps illustrate why this concern might occupy Sara's thoughts more than her feelings about the holidays themselves, her travel preferences, or the general fun associated with winter in a specific location like Colorado.
