[Az-Geocaching] Neighborhood Park Cache

Team Omniterranaut has now been to the area of the second part of Neighborhood Park Cache twice and have searched the area thoroughly but couldn't find anything. We followed the hint on the website (Look for the word Lewisburgh...) and still couldn't find anything. Can anyone offer me any additional hints? Any assistance is appreciated. I dont want anyone to give away the location, just want a hint so hopefully I'll have a better idea of where to search next time.
Thanks.
