Great pictures, Ron. I like the Erythronium too, and the strobilus of the Equisetum. We have a very similar Erythronium (albidum) here.
I see that was taken with the 100 mm f/2.8 L lens. I only have a few lenses for my 7D, but I'm convinced that's the best lens I own, even if it's not the costliest.
