I'm new to bows and I'm looking for a range where I can sight in 40-60 yards. Where does everyone go?

If you have a hunting license, most WMA's with ranges have an archery area.  I know Clinton has one.

Pretty sure Cherry Ridge has a range, but you need to be a member or be guested in by a member, think it about $25 for the day, you can also shoot while there.

Get a hunting license - Black River WMA I think is the closest to you.  

I think there's a private Archery club up your way too - http://www.bloomfieldarchers.org/ 

They practice at Brookdale Park.
