After a google search, I see that there are two Geocachers who cached in New Jersey. One is named "Leo LS", the other is "PRO LS". They have evidently written their caching names on a smiley swag signature item, and placed it in caches. There's also a "THO LS". They have cached together.
Cool! I'll try a google search again then. Thank you! I found the first name, but didn't know that the other two were names also. I'll have to let them know that I found their smiley. Thanks!
