I doubt there is anywhere else in the United States where you can see so many 747's in one day. Expect to also spot MD-11's, 777's, 767's, 737's, and if you're lucky, a DC-3 or DC-6. Boeing's Dreamlifter even makes an occasional visit!
From Point Woronzof you can see aircraft landing and departing from runways 14/32. The top red X is my favorite spot. Just pull over where you see a gate with a chain across it on the north side of the road. Walk up toward the bike path and you'll be able to look down on the runway. You are so close you can smell the jet exhaust and hear the wake vortices swirling overhead.
Here are some shots I took from the Point Woronzof locations a few years ago:
