Awesome! Can't wait to hear about it!
I was thinking... my 8-year-old son needs a pack. I wonder if I should build him a G4... it'd be a fun test run, and a really nice pack for my son! I'd just make it out of cordura nylon so he doesn't tear it up. He has a 12" torso right now, so I figure if I shrink the height and width of the pack by about 30%, it should last him a few years.
I'm joining the G4 Yahoo group... thoughts on that?
