DEER!

There's a sign on my way home from work. You know, one of those yellow signs with the jumping deer on it. And then underneath the deer silhouette there's a distance posted. So you know how long you should watch for deer.

The sign I'm thinking of says "Next 2 3/10 miles"

Do the deer automatically stop when they hit that 3/10 of a mile?

Hey Gary stop!
What's the matter George?
You've gone 4/10s of a mile!
Well crap! Now I'm gonna get a ticket.
