Night Reflector cache

I had never heard of these but this is a great idea. Give coordinates to a trail head of some type, or an open area would work, maybe. Place tiny reflectors to the cache. This would be great fun for someone and fun for you to read the logs... especialy the logs of people who didn't read the page and came during the day ;) The reflectors you want are called "Thumbtack reflectors." I hear you can get them from hunting stores like Sportsman's Warehouse.
