Hi Flying Owl! I found you at an OC Grill Event in Berlin and will move you along (even though I don't understand your mission).
P.S. I dropped this Geokret in gc1v2w (Marienfelder Gipfeltreffen) on 18 Sept., but didn't get around to logging it until much later, i.e., on 29.9. I hope there's not too much confusion. Sorry!
Found it in "Probeturm", Linz, Austria. This cache is quite popular, I hope it the next one woh finds it will log it.
