Re: Is this possible? Checker from a list of caches

As you probably noticed, we've put out a geocaching trail (the PET trail) of 60 (so far, will be 70) caches. We'd like #70 to be a "finale," where folks have to accomplish 35 of the 70 to claim this 70th cache.

(We picked 35 because each of us will only be able to claim 35, as we alternated ownership.)

Is it possible to have a checker created from a list of GC codes we give you, or a public list we create and give you?

Thanks for answering this not-yet-a-checker question.

This will not be allowed as a challenge cache

Please read 2.12.11. Specific Lists

Not acceptable

A challenge based on elements under the cache owner’s primary control is not acceptable: examples, my favorites, my caches, bookmark lists, caches by this owner, or this group.

Thanks.
