Tulip 13 Mystery Cache

This Tulip series is to celebrate the 1^st annual Tulip Festival Clean Up CITO.  I hope this CITO will become an annual event.

This series has 29 caches plus a bonus multi for a total of 30 caches.  The 30 caches consist of 9 traditionals, 20 puzzles and 1 multi.

The puzzles should be fairly easy to research and consist of Wamego history.  My hope is that you will learn a little more about Wamego. 

NOTE:  The area east of #23 is quite eroded and erosion is very close to the road is some places and the road south looks more like a trail through the field than a road…  The road just south is a better road.

And now on to the puzzle:
