Thanks for all the suggestions so far.
incorrigible, I've been reading about your dd's scouting book, and I will take a look at it when I have more than a minute.
mommy212, we are a ways outside of Olympia, in the opposite direction from you. Oly is our hub of out-and -about activity, but still it's quite a commitment to get even that far. I'm not dismissing your offer, I just need to start up something really locally so we don't have to drive so far for yet one more thing. Eventually, though, I would be open to doing activities somewhere between Oly and Tacoma. Keep in touch! I've been a regular on the HS and US forums.
We will be starting 4-H this year. For this, I'm visualizing something like a homeschooling co-op, but based around outdoor skills and welcoming both our homeschooling and schooling friends (and their friends). We'll see. I want something that doesn't have badges or achievements (beyond the skill itself), just fun activities.
