The posted coords are bogus!

There's nothing there for you to find, nor should you ever play in the middle of State Street.

The only way to find this geocache is to complete the Adventure Lab named "Welcome To TRICKFORD!", located here in Rockford, IL. You'll have to have the Adventure Lab app downloaded to your mobile phone, and you'll sign into it using your geocaching.com username and password.

From there, you'll be able to see the "Welcome To TRICKFORD! (A Cheap Trick Experience)" Adventure Lab set. You'll be rewarded with parts of the coords for every stage you complete, eventually leading you to the final location of this bonus hide, where you'll be able to find a physical container, sign the log, and claim the find!

This cache can be found at N 42° 16.ABC W 89° 00.DEE
(Yes, you read that right. There are two E's at the end of the west coords)
