<p>It is really quick to take a cab to and from downtown, isn’t it? If a group gets together and shares this cost (maybe they go in on the train and cab it back), it doesn’t seem as though it would be too prohibitive to do this once a week or so. I know I would be willing to give my daughter an allowance to do this.</p>
<p>A cab from MIT cost me about $25 since the T stops running at 12:30ish (which is insane).</p>
