What Am I?

I’m red, silver, blue or green,

Sometimes not able to be seen.

The grass is what hides me most,

Guess what I am, you may be close.

A good hint to get you going,

I can be shredded up when mowing.

Along the side of the road I lie,

You see me when you drive right by.

I can be big, and sometimes small,

Usually, four and a half inches tall.

I’m filled to the top completely full,

I’m not an old brown rusty tool.

I rhyme with, pan, man, and ran. . .

Because I happen to be a can.
