Some other things... during down time... or while you are thinking on the field...
I've been wanting to get into roasting coffee beans... that might also include nuts... to sell within the region / county...
A smoke house? Making your own bacon? My dad surprised me the other day. He has smoking some fish and pulls a brick of cheese out of the smoker... it was a little bitter first day, but once the flavours settled second day, man was it good... he'd already made his own bacon last fall and it was really good...
Woodworking? My dad got into making his own wood furniture... I've got a plan to make my older daughter a wooden doll... make benches, or bird houses (purple martin houses are still popular, I think)...
Photography? Video? I'll go out with a camera and take pictures or videos... This one time... back on the farm... my dad and I took dynamite and would remove trees from the property and get rid of some beaver dams... great to video and show the friends...
River close by? Get a canoe... Build a brick BBQ... I was in the middle of making a combo BBQ/smoker/fire place before bomb drop... it was for GAL, before I even knew what GAL was...
Garden... even if it's high density... wall gardens, potted gardens... flower gardens... plant some trees... do some landscaping on down time... get some crushed rock to spread on the yard and make yourself a rock garden with pond...
