I was told in official chat last night that caches on elementary and secondary school grounds are not permitted anymore, so any of us that were considering it might have to reconsider. Existing caches are grandfathered unless there is a problem reported.
I would assume if the school decides to place one on their own property, as is the case in the cache at the China School, an exception would be made. Not sure how this applies to hafft adopting this cache, hopefully it is still ok.
Also, lighters were added to the list of items that are not allowed in caches.
Dang, there goes my plans for that pocketknife/lighter theme cache hidden behind the steps at the local school.
