Parents, how do you manage summer breaks, who takes care of your children when there is no school?

When they were younger, my wife and I basically had to work different shifts, although there were also long stretches where I just worked less(because I had found ways to make good money like so). Once they turned 6 years old, Boys & Girls Club was a lifesaver. During the summer, the kids actually prefered to go there on days we didn't have anything fun planned(nor $$$ for activities).
