yes.... it takes time to set up the proper pq's for a road trip. trying to get the distances down such that you can get caches near a particular route. If you drive anywhere close to cache dense areas (big cities), a 500 mile road trip could take 5-6 pq's and sifting, sorting, load into GSAK, export, load into expertGPS to see what you have, then tweak and tune the queries.
It would be much easier and effecient to be able to ask for what you want right up front.
My 2 cents worth!
