Heh heh. I'm a girl and I like to measure, too. Only, I'm more mass-conscious than length-conscious.
(Could be because I'm vertically challenged but not massively challenged, unfortunately! LOL!) I like to make pretty growth curves from my mass data. Mass data are SO much easier to collect, that I gave up on length data long ago. But, I've got a bunch of '06s that I could get length data on for comparison. If I have time this weekend, I'll do so and report back.
