Where can I buy dry ice?
I will be driving to SF later this week and really want to bring home a cooler of my favorite gelato packed in dry ice. Does anyone know where I can reliably get dry ice? I'll be driving up from the South via 101 and hitting the Ferry Building and North Beach area. Not real comfortable with wandering around in the city, so would prefer to buy it on the way up or someplace easily accessed. Thanks for any help!!
