martin,

EXCELLENT IDEA!! I've often thought about doing something similar once my girls are a bit older.

Possible indoor activities:
1. knots and lashing
2. first aid
3. raising frogs (kits can be purchased on-line)
4. eating frogs once they mature 9may be a bit much for some kids)
5. tanning leather (any roadkill around this time of year)
6. making assorted campstoves (pop can, wood gas, etc...)
7. the "What If/How Could..." game (what if you a blizzard trapped us in this building with no power. How could we stay warm, fed and hydrated?)
8. basket weaving (useful skill!)
9. sewing/mending
10. whittling
