You could also teach fishing to kids. What about hunting or foraging? I’m a rock freak also since my Grama taught me to beachcomb for agates on Olympic Penninsula in WA. I used the meager amount of money my dad left when he passed way for a commercial rock tumbler then picked up a combo unit (slicer, grinder, polisher) at a swap meet but recently got new portable equipment with first stimulus check. Man for our old church in Washington had a rock shop and he taught lessons in cabochan and wire wrapping. My husband and I hd a house in AZ for a year as investment and I joined a rock and gem club and learned alot about rockhounding. I’d like to teach kids these skills, the. There’s sewing, pottery, carpentry, etc;
