Pocket Queries are GREAT. I love them, really. It makes it easy to get a ton of caches in an area.
But it's not enough anymore. Here's what I really want to do:
* One query. All of the caches in Washington state that I haven't found. Updated every week.
That's it.
Here's my reasoning.
* With the advent of GPS devices like Garmin's 600/650, which can hold millions of caches, the limiting factor now becomes this website.
* There are so many caches in many areas (like Washington, where I am), that it's difficult to have a significant geographic area in a single query, unless you spend a LOT of time tweaking the queries.
* Many weekends, I just want to get in my car and drive, and see what caches are there. It's not really possible to do this without spending significant upfront planning. I have to figure out where I'm going to be, create a new PQ, download it, etc. If I just knew that my device had all of the caches already on it, how much easier would this be?! As it is now, I just don't bother sometimes.
* Allow far more spontaneity in general.
I know it's possible to work around these--I could create multiple queries, but figuring out how to get suitably wide coverage without getting overlapping results is next to impossible, and this is just too much work in the end.
Alternative:
* Generic, downloadable files that contain all caches per state/country/etc. It would contain things you've already found, but I think most devices recognize that anyway.
