I second the headlamp idea. My youngest loves the one we have. They can be a lot of fun for playing outside at night. Cute flashlights would be another alternative......or the little lanterns - great for reading the books while they are camping
I love, love, love the bracelet idea someone had for their daughters. My DD has a Bauble Lulu (she has, up to this point, been to hard on jewelry to try anything expensive) and she enjoys it.
I'm going to look into those roasting sticks, myself. My kids love a "campfire" even though we aren't campers. Those would be awesome!
I'll add what I have set back or picked out so far:
YDS is done. He is getting the little LED alien toy story game, 3 leap frog books for his TAG reader, a
LEGO buzz lightyear watch
DD is done. Already on hand: AG Sugar dog, 2 AG fashion scrapbooks (Samantha and Felicity), AG Coconut joke book.
ODS....yeah. He is 11 going on 21 LOL I *think* I will get him some comic books, an iTunes card (but would need to give DD one as well... I might get the 3 pack and use the third myself

), and XBOX points.
All 3 will get candy and money filled eggs - I usually buy a couple of small bags of candy, some $1 bills, and fill eggs myself. Sometimes we hide them in my mother's yard and let them hunt while we sit on the porch and talk. If the weather is disgusting the Bunny will probably just drop them off in the basket LOL
Almost everything I've bought I've gotten either on sale or in the post-Christmas clearances. The only item I bought at full price was the LED game and it was $10 so I'm kind of tickeled!!
