This cache was inspired by a lot of research that I did on interesting Multi-caches, and the fact that we had some of the twinkling stars in my camping gear!
We also wanted to encourage the use of the compass and point-and-go features of the GPS that we have! You can put in zero relative and sight along the line to help find the star.
George and Izzy LOVE to do things together, so this hide is designed to encourage geocaching with a friend: It will make it much easier to locate the hide if you have two or more people
It may help to have a friend stationed on the other side to mark the location once you have it. you will see what we mean when you get there... 
When we hid this, we tried several different lights to find it. Most small flashlights/headlamps were not up to the task or making the star twinkle... But our small LED spotlight found it easily, as well as two other very bright lights that we had with us. You will probably have them with you as well.
