On the way up we decided to grab Lower White River Museum State Park, as we were passing by. Lots of neat stuff in there from the bygone erra of steam boats and such.
After grabbing lunch we moved onto the Herman Davis State Park. It's a tiny (less than 1 acre) park dedicated to Herman Davis, a World War I veteran. The park's sign sums it up better than I can, you'll need to click on this image to make it bigger.
We then headed on up the road to Lake Frierson State Park. Took a nice little hike up the hill. Not much else to do in the park if your not fishing in the lake.
And we ended the day at Crowley's Ridge State Park. Took a nice hike over a swinging bridge as well as several other bridges. Found the cache, but no clue :(. Apparently when they rebuilt the cache after it was stolen they forgot to include the clue. The park superintendent and the new park interpreter were both aware of the cache but didn't know the clue. The interpreter's going to track it down and email me. In the meantime I've reached out to the cacher network and think I have the values.
Then it was WAY up the road to the Missouri border (which actually involved a jaunt through the bootheel of Missouri to Mammoth Spring State Park. We all stood in the middle of "State Line Road" to be in 2 states at once.
And, here's our updated map, we're 1/3 of the way there.
