Has anyone else ever written a National Treasure clue?

Perhaps my two Letterbox Treasure boxes will give you inspiration.

BTW, both clues tell you where to locate the required text needed to decode the message. However, you have to be a little familiar with Ogden to figure it out. Still, someone managed to decode the first message (and tell me two mistakes I'd made) without leaving Idaho, but (fortunately) I can no longer find that particular image online.

This one is one of our favorites:

I believe we were last to find.....there had been some serious maintenance at the location leaving it very exposed but we had a blast solving and finding it.

So once again I watched Nicolas Cage in National Treasure. That movie always inspires me.

That brought back a really old memory.

I have a series of 6 boxes in 3 different parks that is one of, if not the, favorite series of mine: it's #115104
