Cache is a small lockable container.
Lets get down to the nitty gritty!
Gritting lorries are a familiar sight in winter, sprinkling the main roads with salt.
How does gritting work?
Although it's called grit, what is used on the roads is actually rock salt, which lowers the freezing point of moisture on the road surface, so it stops ice forming and causes existing ice or snow to melt.
This cache is guarded by a mischievous elf called' 'Gritty' who lives in a tree and likes to watch the gritting lorries go about their work. In the winter Gritty often throws snowballs at the passing grit lorries. In the summer, he likes to sleep alot. Be careful not to wake him when you retrieve the cache from his home!
