Writing the same essay for two schools?

My essays for Wisconsin-Madison and Indiana are going to be very similar. I already wrote one for Madison, and I’m wondering if I should just follow the same format in the Indiana one. Both have pretty much the same message, that the combination of strong academics and a Big Ten sports atmosphere are perfect for me. I think my Madison essay turned out good, so is there any reason to come up with a completely different topic?

It is fine to use the same basic essay as long as it is tailored appropriately for each college.
