“. . . A frozen monument if you will, erected in a semi-stately homage, symbolic to all the keepers of the grill out there, who do not, and will not, save for a trip somewhere with a blue tag on their big toe, take the winter off…. A tale of fire and ice.”

1. What does the Blogger mean by “save for”? 2. What is the definition of “save,” used in this context? 3. What does the Blogger mean by “trip somewhere with a blue tag on their big toe”? 4. Is this “trip” literal,metaphorical or both? 5. What does a blue tag on a big toe symbolize or represent?

. . . to all the keepers of the grill out there, who do not, and will not, save for a trip somewhere with a blue tag on their big toe, take the winter off.
