4350 North Grand Lake Hwy
Posen, MI 49776

We are located in Presque Isle County in the North Eastern part of Michigan's Lower Peninsula approximately 1/2 hour north of Alpena and 20 minutes south of Rogers City.  The closest highway is M65 which intersects with M32 and US 23.  We are located at the dead end of Grand Lake Highway approximately 2.5 miles west of the intersection of M65 and Grand Lake Highway.  There is an older abandoned house right before us, keep going just a little further.  Our mailbox location confuses some because it is down next to the old abandoned house... You can't go too far, we are at the very end.  The map below shows us on the left side of the road, but we are on the right.  The closest intersection is Leer Road and Grand Lake Highway approximately 3/4 of a mile.  Please call us at (989) 766-2593 if you need additional assistance in finding us!
