the leprechauns:It is definitely a good idea to upgrade your filter and to change the oil every 3,000 waymarks.
I'm really glad that ODragon included a picture. A picture can provide so much detail, saving hundreds and hundreds of words. And you all know how many words I can use when I don't even try. That picture tells me everything in one tidy package. Dare I say, it could be a picture or take something like a thousand words to let me know what he was getting at.
Hmmm... there's an analogy in there somewhere, maybe a similie.. metaphore, expression, something.
Anyway, sure this would expedite filter creation. One of Waymarking's strength's over Geocaching is the filtering and returning results that appeal... this does this in spades. Spades are another thing that them Geocacher ain't got!

p.s. In Canada, we only need to do our filters every 5 000 Waymarks. Metric RULES!
