My mother treated me to Baltimore's Aquarium in Inner Harbor for my birthday. We couldn't get in the aquarium right away, so we sat down in a restaurant where a pigeon later walked in and started eating the table scraps on the floor...except the shrimp (the restaurant had outdoor tables). Then we went to a nearby office building with an observation floor...great views of the city.
In the aquarium they had a 4-D show with various special effects like air jets that blew on the back of the legs and--get this--bubbles. A couple of kids couldn't handle it, and one even said, "Not again!" One of the exhibits had an alligator

sleeping on a log, and another had a white fishing popping its head out of his hole

. One of my favorite exhibits was the one containing poison dart frogs...the ones with enough poison to kill 10 humans

.
On the way to and from the aquarium, there is a convention center, and there was some sort of event going on. People were dressed up as various anime, comic and video game characters. Among the characters portrayed were the following:
-Speeder Racer
-Sailor Moon
-a couple of Naruto characters
-Iron Man
-Batman
-Link
-Captain Falcon (wished I asked him to do a Falcon Punch)
-Spider Man
-Dr. Weird from Aqua Teen Hunger Force
-The Ancient Minister from Super Smash Brothers Brawl's Adventure Mode
