Our visit to Gray Fossil Museum and active dig was a fun side trip. Its not a very large museum so plan on needing about 2-4 hours to see it all depending on how interested you are in such things. Be sure to take the guided tour of the active dig where you will learn much more than just browsing the museum. Our guide was extremely knowledgeable and interesting. The museum layout is airy and the glass walls allow a view of the detailed work the volunteers and scientists do. The temporary "peanuts" exhibition was a fun extra.
