You know, we could have fun with this as well.
Instead of all these helpful signs, how about just adding a few white dots and arrows down below, so that the trail leads in endless circles about 10 minutes above the museum? We could even post some strange symbols like in the Blair Witch Project, just to make it spooky.
That way the dumb ones will just do laps and give up, exhausted, down where it's safe. People with a guide will skip right past the decoys.
Even more fun, what if we downloaded some recorded sounds, like tigers roaring, rattlers rattling, maybe even an elephant trumpeting, then played those sounds a little way off the trail in the predawn darkness when people went by.

Imagine the trip reports we'd see posted here. This could be sweet.
