I have to credit my mate with this one. After reading the current strip, she started up with a case of the giggles, and when she finally got under enough control to explain she said she'd had an image of Dusker finding and raiding a picnic basket.

The clincher is that said basket would have the initials "YB" cut into the side.  

Did I date myself with a Hanna-Barbera related reference?  

Happy travels.

Not quite.  It made me think of Yogi Bear which I now see what you where referring to, and YES I could entirely imagine that!
