My parents were farmers and I did grow up going to farming conferences, sometimes sitting through sessions and other times playing hide and seek with my brothers.  Good memories.  
But DH and I are both city folks in professions where you really do not bring your kids to conferences.  It even says specifically that young children are NOT welcome. Older kids can come, I guess, but they would have to have to register at $300 or so. So we don't take him along with us!
I should just add that there is no way that I would have gone to this conservation conference if it weren't for DS. He saw the agenda and got so excited and kept asking to go.  I don't have a problem with the group (they're great folks), but I just have a lot of other interests and time commitments.  At the meeting I introduced myself as DS's driver.  I was the one tagging along, not the other way around.
