Before you go to the trouble of driving out to the Observatory, look up at the sky and make sure it is clear. Also, take along a jacket. It is usually cooler than you expect.
Finally, since the gate to the South Farm is often locked, please arrive by start time to ensure entry.

Viewing the International Space Station:

When this behemoth passes overhead, it outshines most of the stars in the sky.
To find out when it will be visible in your night sky, check out these links:

Directions to the Observatory:

Find the intersection of Blackjack and South Farm roads. (It is the red light closest to Starkville's only roundabout.) Proceed south on South Farm road until you see a marker telling you to turn left for the observatory. The observatory will be on the right hand side.
When you leave, there is no need to turn around; simply continue around the loop that takes you back to South Farm road.

N.B. On the South Farm beware of ditches along roadsides.
