Short Riddle

I am a place to stop,
Yet my name says I'm a place to go.

What am I?

(Hint: Think Car)

(Hint: Where might a car be when it's stopped? The name of the "place" sounds like the car should be "going". But it doesn't have the word "go" in it.")

Riddle

Many love me whether I am blond, black or red
Make me wait too long and I may lose my head
Some say I am smooth or even cold
I can cause confusion, or so I am told

I can disappear like a crazy magic trick
No skips or jumps, just hops without a pogo stick
Which makes me more or less bitter
As I cause my share of road side litter

What am I?

Does the Groundhog know the Answer?

I come in different shapes and sizes.
Parts of me are curved, others are straight.
You can put me anywhere you like,
but to do my job I only have one right place.

What am I?

Hint #1: It's small enough to fit in your hand or pocket.
