During this hike we pondered such things as "Who do you call if you trip over your feet on the border between two states?" and "Why do those cornstalks have feet?"
We encountered the cornfield about a mile or so into the hike and noticed the feet on many of the stalks. Not all were intact though. A little Internet sleuthing when I got home reveals that the 'feet' are a tertiary root system called 'brace roots'. Turns out corn has two root systems normally. If the brace roots appear it likely means the main root system is dying. It's the corn's way of saving itself. At least that's what I took away from this article.
I still don't know the answer to the first question about falling but I didn't try all that had to find an answer either.

We continued on the trail in search of the Tri-State Marker. We found two markers. After I got home I did some more sleuthing to figure out why there were two markers.
Approaching more or less from the southern most entrance to the Tri-State Trail as we did, first you come to this stone. We realized though that it only had a "P" and an "M" inscribed in it and the date "1849". If this was a Tri-State Marker where was the D? We assumed at the time it was a fake out marker or a mistake of some kind. Turns out it is not. The original marker was wooden and placed by the original Mason - Dixon party in 1765. That marker was replaced with a stone marker in 1849 (the date inscribed) and only identifies PA and MD because in 1765 DE was part of PA.
The original wooden marker was a Mason - Dixon line marker noting the line between PA and MD. It is not referred to as the Tri-State marker because it does in fact mark the meeting of the three states. However, that was not it's original raison d'ĂȘtre.

I found references to the smaller marker we found just past the Dixon Marker. IN the photo you see Julius dancing around three states. But it's unclear what it is/was for. This smaller marker contains a plate on top that indicates it was placed by the US Coast and Geodetic Survey in 1935. Most references I could find to it do not make any statements as to why it's there. Yet the letters MDP on the plate led us to believe it was the 'real' marker. I'll have to do more research another time.
All in all we had a lovely stroll through White Clay Creek Preserve (in PA) and White Clay Creek State Park (in DE). With the very brief foray into Maryland the was a three state hike!
Keep smiling and Keep Moving!
