Ah, now I know what happenned to all P.caerulea and P.lutea that
used to grow along this road. One of the reasons I had wanted to
be sure to re-visit the eastern side was to see all the butterwarts
growing along the road. I have seen pictures of that road in which
the sides of it were completely deviod of green from all Ping flowers.
I was very disturded upon my return to find not a single Ping. There
were still a couple hundred (I say this because I'm sure there were
many plants that I didn't see) of them growing along rail line by the
entrance but this is a very small population compared to what was
there only a few years before.
