Summer Vacation? Should it be removed?

Summer has always been a time that has brought great joy to all the kids and teachers in America. It is a time to finally stop worrying about all the grueling school work and just relax by the pool and take in the next couple months of freedom. Although I love summer as much as the next guy, does it really benefit society to take all that time off of school?
With the summer vacation students have a couple months to forget everything they had previously learned in the last 8 or so months in school. Then when they get back to school they have to spend at least a good month to catch back up so they can remember everything that they had forgot while vacationing in the summer. We all know that the more people use the knowledge they have the less likely they will forget about it in the future; so why not cut summer vacation entirely and just have school year around? It would not of course be twelve straight months of school. There would would weeks off intermittently where kids can relax, but not the a huge amount of time like in the summer. This way kids can have their time off but not have to waste time making up what they forgot in the summer; and the teachers will be able to fit in more material.
Although this seems all nice and dandy would it really work? I believe it would definitely be hard for the American society to grasp since they are so used to having their summers off. Plus Although summer vacation might hinder the learning curb for some students there are tons of summer camps and other activities for kids to learn from and make themselves better citizens that kids could not otherwise do in school. Also kids need a break from the pressures of school and have time to relax. In the end I believe taking away summer vacation would not be as beneficial as keeping it.
