Where Sandra Garcia Gomez lives in northwest Spain, snow is unheard of and the few mountains they have would barely rate as a bump along the foothills of Colorado. That’s why Sandra’s family of four couldn’t wait to visit. Now they might not be able to return home as planned. The family’s long-awaited sojourn to visit childhood friends in Centennial quickly turned from a 15-day snow frolic to a frantic blitz of emails and phone calls trying to get back. “It’s been impossible, frightening and unbelievable all tied into one,” said Garcia, a part-time pharmacy worker in the coastal hamlet of Sada in Spain’s region of Galicia.
