I used Mapquest to find the route from the Hawk and Dove bar to Kennedy's apartment. The image is here, and if someone could post it, I'd appreciate it. Heading west on C Street, he could've turned right on either 2nd Street or 1st Street to get over to Independence Avenue.
Mapquest picked 2nd Street, and Kennedy really should have, too. Instead, he continued west on C Street, weaving badly and forgetting that on the other side of the intersection with 1st Street there's a barrier in the road. Post #549 on this thread has a picture of it. Instead of turning right onto 1st Street, he plowed into the barrier.
This was half-way between the bar and his apartment. Notice the location of the Capitol. If he was headed from his apartment to the Capitol, what was he doing down on C Street?
