I started in 2009 and enjoyed it alot expecially night caches for one reason or another I stopped. I started getting the itch again and I guess the format changed or I just don't remember. I can't find any night caches anymore!!! I live in the 60638 zipcode and my kids enjoyed the night caches the most, is there a sertain way to locate a night cache? I am a premium member and I also have the geocahe app on my android phone.
