I think my Dad and my sister are the ones who got us into this "caching thing." We have infected my other sister, my husbands parents and a few friends.
Sorry to say we can't hunt as much as we would like because that thing called "life" gets in the way, but we try to go as often as possible.
I am usually the instigator of it all, but as soon as I mention it, my husband and kids are raring to go. Maybe in September when both the boys are in school, my husband and I can get out more by ourselves!
