I'm lucky (maybe) didn't have kids until in my 30's, so while some folks (like you) my age send kids to college, mine are still in grade school and a jr. high girl. It'll be my turn soon though.
I didn't have my first until 31, too busy working and traveling with the racehorses. DH will have to work forever as our youngest is in 6th grade! oldest graduates in May, then #2 starts college... PHEW!
