At the risk of sounding old, back in our day, summer vacation meant no school. Meaning no homework. Meaning no summer reading lists, summer "mindwork" or whatever other euphemism teachers want to come up with for giving kids a bunch of busywork meant to keep their minds from atrophying over the summer but which in practice is just something that parents nag their kids about all summer, until the weekend before school starts up again, at which point the kids do the most half-assed job imaginable at rushing through a stack of paperwork. If only teachers would just let kids be kids during the summer — or have them exercise their creativity at art classes like Oil & Cotton's. Ranging from $10 hourlong craft classes to multiweek advanced sketching classes to four-day songwriting workshops, these instructional camps give kids something to look forward to while also keeping them from going brain-dead in front of the tube.
