The establishments in this section are easily accessible by public transportation; given the difficulty and expense of parking, it's preferable to take the T everywhere. Even the Kennedy Library, which has a large free parking lot, operates a free shuttle bus that connects it to the Red Line. To maximize your enjoyment, try to visit these attractions during relatively slow times. If possible, especially in the summer, sightsee on weekdays; if you're traveling without children, aim for times when school is in session. And if you're in town on a July or August weekend, relax and try to convince yourself that you love crowds.
