Since there's a limit on how many can be run per day, I always break things up geographically into 4 or 5 big chunks, trying to get minimal overlap (requires moving centers around from time to time). Both of my Garmin units will let me browse around on the map and identify caches in a particular location. So if I were in the peculiar situation you mentioned, I would just browse to the park in question, put the pointer on the cache(s) there (eTrex) or poke them with my finger (Dakota), and find out which ones they are. Another way to segment PQs into 500-cache chunks without having to move centers is to segment by time. I have 5 PQs, all the same center point, all 40 km radius, but each of them pulling a different date range. I came up with the ranges by varying them until I got close to 500, knowing that over time this number will just go down as old caches die off. Last week, for the first time, I had to go in and readjust as my "XXX-Present" PQ hit the 500 cache limit. A lot easier than figuring out centers on a map and no overlap.
