Take highway 10  out of Fargo heading east toward Detroit Lakes.

You will come to an intersection with lights just past the Wal-Mart in DL ... take a right ... it's highway 59.

Go south on 59 until you get to the sign that say Vergas Road ... turn left on the Vergas Road ... continue along until you come to Camp Trowbridge ... it will be on the right. 

If you get to Vergas you have gone too far.

Someone will be there to signal the place.

And you'll be there.
