Ron, I'm really enjoying your great photography. Few people stop to
admire the beauty of wild roadside plants. Of course, on foot or
bicycle one has a far better chance of seeing them at all!

Your web page could be a good resource for identifying roadside
flora of northeastern US and adjacent parts of Canada. Adding the
scientific name of the plants would make it far more valuable, since
common names not only differ geographically, but the same name is
used to describe completely different plants in different areas.
You could also indicate whether they are natives or aliens. Not
to be too critical, but many of the plants you've photographed
would be more accurately called wildflowers than weeds. The
technical term for herbaceous (non-woody) plants other than
grasses is forbs.

Have you spotted any columbines yet (Aquilegia canadensis)? Since
you're a few weeks ahead of us here, I'd expect they'd be in bloom
there soon, if not already. They like semi-shade.
