There are times I'd like more...and then times it's hard to imagine how we'd manage more....especially with both of us working. Right now, we have a friend as a ranchhand, and she maintains the place for room and board (and commission in the shop), and pretty much whatever fun stuff we all do....so she really doesn't want for too much. Our two kids are home now, and looking for work, so they've been helping on some of the needed catch-up tasks. Otherwise, we're pretty busy with ranch chores on the weekend.
Eventually, we may look into getting some or all of the land behind us. Would give us more pasture space, and a lot of crop area (and we'd probably do some hay growing)...but really, I'm not seeing us having the time or funds to do that anytime soon. That plan would require one of us working from home at least...which is possible, but not in the foreseeable future right now. Once the mortgage is paid off, we may go that route though.
Any other siblings regarding your inlaws' place? May be something to at least plant the seed (but you may have to agree to allowing other siblings to come if the SHTF)....
