The trail head is on the South side of 52. Google navigated me about half a mile West of where the site entrance actually is located. So drive slow to not miss the turn in, and go a bit further East than what is pinpointed on the map.
At the trailhead, there was a sign in sheet, the posted display map, and a picnic table in a waterlogged/flooded area. There were porta-toilets at the air field, not at the trailhead, but they may have been locked. The air field is a ten minute walk or half a mile in from the trail head.
The field looked recently mowed, but the trails were overgrown by a foot of grass or so. The trails were accessible to horses and ATVs. The soggy ground at the entrance flagged my attention that I may have trouble hiking on foot, so I stuck to the gravel path that dead ended at the air field.
I saw two groups of sandhill cranes and no trash. I saw a dumpster that may have been locked up - so try to hike out with all your waste. Thank you for managing the area!
