It doesn't open until August, but already it's a sight to see. After fossils were discovered in 2000 during the widening of the nearby highway, plans were made for a natural history museum outside of Gray, TN. Scientists estimate the fossils are 4.5 to 7 million years old. If the museum exhibits are even half as interesting as the building itself, they'll have quite an amazing attraction for Washington County and East Tennessee.

Directions: From I-26, take exit 13 (Gray) and head west (turn left, away from town) on Route 75 (Bobby Hicks Highway) for 1.8 miles. The museum is on your left.
