The field (Graves Campground) is located south of Brooklyn off of M12 between Brooklyn Rd. and M-50 just across from the MIS main entrance. Enter through the main MIS entrance on M12. Follow the signs for "Check In". Be sure to stop at the guard shack and sign the MIS waiver form. Once you're through the gate you'll proceed forward 100 to 200 feet. Turn to the right. The road will take you to the Tram # 9 station. From there you will see the tunnel that goes "under" US-12, follow that to the Graves Launch Site.
At the end of the day, you may leave the way that you entered.
Drive back to the MIS Security building. You'll see a Yellow grid painted on the asphalt. Drive up to that point & the gate will open so that you can leave for the day.
