While in Heidelberg on a tour, I found a cache a short walking distance from the castle, and a short distance from the edge of the street: "Castle cache by Carrie,Rob, and Jessie (GC890F)", still active and recently found. I came close to a couple of caches in Munich, near the Olympic site, but could not break away from the group to go chasing into the woods. The cache I found in Frankfurt was about 0.25 miles from the hotel... a good reason to get up early and go for a walk.
I loaded as many caches from PQ's as I could in a reasonable radius around our hotels and caches on a route as POI's in my Garmin MAP60CSX. Without WAAS, the error is higher and some caches should have been easier than they were and resulted in more DNF's. Lots of fun though.
