Birdbrains by Thom Bluemel for July 28, 2018

That big rock is days, perhaps weeks away on your hands and knees.

Man, this desert pub crawl is brutal.

I think he is presuming a lot.

Livingston is probably thinking he has to stop hanging around with this looser!

That big rock on the left looks like a skull.

And the rock just above Livingstone (appropriate name for this) is a face looking up and that big mesa is looking to the right.
