Tonight I took a channel-surfing approach to fireworks: I watched a little bit of each of many displays. By "many", I mean somewhere between 18 and 24.
I identified 18 different launch points for skyrockets from the back window on the third floor of my house. I later spotted four more distinct launch points visible from the front window. When the Inner Harbour show started (which is partically obscured by trees and a church, from my window), I hopped in the car, hit I95, went just past the beltway, got off on the I195/166 exit, cruised through the Park And Ride (from which two different fireworks shows were visible ... Ellicot City and Catonsville? Arbutus and Catonsville?), got back on I95 heading North, and figured that if I timed it right, I'd see a reasonable portion of the Inner Harbour display through my windshield. While driving, I saw two more displays that I'm certain I didn't see from my house, and a couple more than I might have also seen from home.
While I'd long thought that the MLK Ave exit flyover would be a great vantage point, I hadn't actually planned on stopping there because there's not that much of a shoulder. But there were enough other cars parked along there (and several other points on I95/I395) that I figured I was partly protected by the other cars. So I watched the rest of the Inner Harbour display from there, along with a smaller display in a direction somewhat East of BWI.
I drove home figuring that was the end of the fireworks, but I headed up to the third floor just in case. There were still a lot of bursts to the South and West, finally petering out around 22:40.
I didn't get any photos, but I got a good show ... or a couple dozen. (I'm not sure how many different shows I saw, because some of the launch points had a sufficiently narrow angle of separation between them from my viewpoint, that they could have been opposite ends of a high school football field if they were closer to me than they looked. (This is why I say "18 to 24" displays.) Many of the launch points were within Baltimore (as were all the ground displays that I saw reflections/glare from, including one on Pratt Street that I could see part of between the houses). Either a lot more small communities staged their own shows this year, or a whole lot of private individuals were firing off skyrockets. I wish I had an ultra-wide-angle lens (my widest is 24mm) so I could capture enough of the skyline at once to really show the effect. (For some of these displays I was only seeing the few highest bursts; for others I saw most of the show but at such a distance that it was pretty tiny. Showing all these small peeks scattered across 160 degrees of horizon would have been dramatic even though only the closest would make a good photo on their own.)
I can see a long distance in some directions (those not blocked by buildings or trees). I'm not sure what the show waaaay over on the horizon was; I'm wondering whether I can see Jessup from Lombard Street, or was that Elkridge? It was the right direction for either of those, and a clear shot to the horizon without tree/building interference. When one of the really late ones to the West-Southwest ended, it revealed another in the same direction twice as far away! (That direction is obscured by buildings, so I only got what peeked over the rooftops.)
Some of the late fireworks were really high, which made the more distant ones nicely visible and gave the inside-Baltimore ones a spectacular surround feel.
My original plan had been to go join the crowd at the Inner Harbor and try to get a spot to set up my tripod where fun bits of skyline would be in the frame, but I wimped out because to get there early enough to get a good spot (and parking near enough to lug the camera bag), I figured I'd have to deal with the record heat for too long, so I wimped out. (Maybe someone else can tell me whether I could've waited until it cooled off the little bit that it did, and still gotten the view I wanted.) But if I'd followed my original plan, I wouldn't have found out how incredibly many different directions I could see fireworks in at once from my house.
I missed the DC and NYC shows on television, 'cause I was hanging out my window or driving around, not doing any literal channel surfing. I heard those were especially spectacular (especially NYC), but I'm glad I got to experience the "surrounded by celebrations in every direction" effect that leaning out my window provided.
