If you get in the brush as much as we do, you also find lots and lots of different kinds of burrs (also spelled, burs). Here's one plant we found just ripening it's burrs. It's so late in the year that we've had a hard time identifying this dude, many of it's leaves are spent.
And from that plant is the result of some deposited on the Grace-ster...
Burrs may be a nuisance, but you have to give 'em credit for being the inspiration for velcro, which comes in very handy. BTW, velcro makes a great stocking stuffer for any dog lover, when you're out and about on Black Friday, BOL!
It was George de Mestral who in 1941 (some say 1948) came up with the idea of velcro after coming back from a hunting trip with his dog who had picked up some of the nasties. Genius dog that was, I must say :) Just think if he wouldn't have picked up those burrs that day, just like Gracie, we may not have velcro in our lives!
