When I was first introduced to Curly Grass Fern back in 79 or 80, while in college, I was given the impression that it was an extremely rare plant, and was therefore very excited to have it identified to me. That actually worked out kinda well, as even though I've found it in many sites since then, I still have a bit of that residual excitement when I find a plant. In fact, I'm heading out into the field today as soon as a co-worker shows up to check out a site we haven't been to in a while. Maybe I'll talk one of the youngins' I work with to show me how to post pics here afterward.
And speaking of the plains, there is a good site there to visit that not everyone is aware of or pays attention to. Turn west from 539 onto Sim Place Rd., then take the right fork onto Beaver Dam Rd. Go down a bit past the homes and turn left toward the large military communications tower. Immediately on either side of the road will be the finest patches of Broom Crowberry in the plains. Gene Vivian showed me this spot back in the late 80s while I was working for him. It was a favorite plant of his and he always loved showing it to people.
