Substitute for Chervil?

I have a recipe which calls for chervil. We live in a small town in Wyoming, and I am unable to find it, either fresh or dried. Is there anything similar which I could use as a substitute?

Chervil looks like a more delicate verison of the plain-leaf parsley, but the flavour is very different. It has a distinct anise-like component which is what makes this herb so special. It cannot be dried successfully, which is why you must use it in the fresh-cut state.
Chervil is easy to grow. It germinates quickly from seeds, or you can purchase plants. It is annual which must be planted each year.
