I think I'm more obsessive about it than my hubby, although he's the one who got us started.
We log as a team, so there's no stat competition. I think he's only been on one hunt without me. The kids and I have done a few without him. I thought that once the kids went back to school, I might start hunting some on my own. I went on one solo and found that it wasn't nearly as much fun as spending the time with my family. Besides, it took me about a half-hour of searching to find the cache. The hubby and kids are *way* better than me at the final search.
When the kids are with us, they run the GPSr. When it's just the two of us, we take turns.
