Big Basin state park in Santa Cruz county is nothing short of miraculous. We counted 167 banana slugs on a 4-mile hike yesterday. Warning: photos 3 and 4 are NSFW.

A poignant reminder that the Secretary of Health and Human Services is not a physician but a conspiracy-spewing, ambulance chaser.
RFK Jr's response to someone collapsing nearby him was to haul ass out of the room as quickly as possible

3/3 It finally flew up into a tree and gulped the prey into its (see bulge in throat) « crop ». New word for me. Didn’t realize hawks gulped things whole. A last resort when pressed for time and trying to avoid losing its kill. It then flew off with this in its gullet.

2/3 Then the hawk tried to discreetly squirrel peg-leg walk away, probably casually whistling. I’ll just be heading out…

Why is Trump shilling for the CBD industry? What the hell is the commonwealth project? How the hell can anyone focus on work with this non-stop dog and pony show?
Track down the Truth Social infomercial. It's jaw-droppingly stupid.
