We are newbies. All these suggests are great! My sister got me started. It helps alot having someone go with you who has a little more experience. You then quickly learn that your GPS isn't perfect. Even when you have 2 of them, you can be way off, the posted co-ords can be off, you can have interference etc, etc. But knowing my sister couldn't zoom right in, made me realize I wasn't doing anything wrong! The more experienced person has also seen some of the crazy containers that are used. If you don't know what you are looking for, you can touch it & not realize it! It's addictive!!
