The hardest geocache for most people to find is the micro cache. The reason is simple – they are very small and fit in lots of places. When you approach a grove or trees and are looking for a micro cache, you know you might be in trouble. To find the micro cache, think like a hider. How would you hide it if it were you? Also, consider that micro caches tend to be hung from trees and are often magnetically stuck to metal, so try that out for size to see if you can knock this cache off your list.
