Hiking in Vegas and Caves

[gobot5]

This is in response to the discussion, a few months ago, where someone posted a long story about hiking just outside of Las Vegas. The author of the post said that he saw "caves" high up on the side of a cliff, with lights that moved around inside before turning off.

I would like to contact this guy, so whoever you are, please respond to this or email me.

To everyone else:
If you have had any experiences with such things, or with underground tunnels, or the like, please share them. Or even if you know someone else's story.
