Easy micro on Darmstadt's west side.
In the spirit of, but not in direct emulation of, the "lame autobahn micros" I've found to the east, I present this cache for the A672. This highway may not be the shortest autobahn in Germany, but it must be on the list -- at 2.5 km long, it isn't exactly a long drive.
Cache is a PETling. No pen; please bring your own. This cache is NOT on the Autobahn -- please do not enter the highway looking for it!!
