I have two small children and a wonderfully GCing wife.
The two children are NOT GC friendly.
I love LPCs.
I hate puzzles. It's fine with me for them to exist, but they should be ignored in density calculations. Not fair to deny me (or somebody else) the right to place a cache because of a puzzle.
"Pushing the boundaries" for me means giving me a way to cache with my kids without it taking three hours to find one.
So those of you who can hike 40 miles a week looking for the hard ones, feel free. Those of you who puzzle, puzzle away. But leave something that the rest of us like, too.
