I started geocaching last year and I couldn't be happier. My husband and 2 children geocache also and it is the cheapest hobby that I have found out there. I pay $30 for the year for a premium membership + $10 Droid App so I can cache on the go. $40 equals 4 movie theater tickets or 1 family dinner at a family restaurant. This is a family activity that we can do together and the only other thing that we pay for is gas (which is kind of expensive) but it's still cheaper than a lot of other activities. Our family is so glad that we got into geocaching and I can't understand all of the complaining for an inexpensive way to spend time with a loved one, friend or by ourselves. BTW, it's also great exercise!!!
